Comparison Table
Epitope mapping software tools turn sequence, structure, and interaction signals into testable antibody-antigen hypotheses through docking, HDX-MS mapping, and peptide modeling. This ranked list is built for analysts and technical evaluators who need clear decision tradeoffs across accuracy, input requirements, and automation, using consistent criteria rather than vendor claims.
PDB2PQR
vertical specialistStructural preparation tool enabling electrostatic analysis of epitope surfaces on protein antigens.
Automated, repeatable PDB-to-PQR model generation tailored for Poisson–Boltzmann solvers.
PDB2PQR accepts PDB inputs and produces PQR outputs used by Poisson–Boltzmann solvers, which supports downstream electrostatic potential calculations tied to antibody–antigen interface analysis. It adds charge and radius assignment and standardizes atom typing so the resulting electrostatics inputs remain stable across repeated runs. That pairing fits pipelines that treat electrostatics as a feature for mapping and comparison rather than a visualization-only result.
The main tradeoff is that PDB2PQR does not compute epitope residues, epitope bins, or peptide tiling by itself. It works best when paired with an epitope mapping engine that consumes electrostatics results, such as an interface-scoring or structure-based mapping workflow. A typical usage situation is generating PQR for multiple antibody–antigen complex structures before ranking candidate binding regions by electrostatic complementarity.
- +Deterministic PDB to PQR conversion for reproducible electrostatics inputs
- +Automated atom typing and parameter assignment for consistent Poisson–Boltzmann runs
- +Batch processing supports throughput across many structures and complexes
- +Strict format handling reduces ambiguity between structure preparation and calculation
- –No built-in epitope mapping, residue ranking, or epitope binning
- –Configuration choices for charges and radii can require expert attention
- –Does not replace a structure visualization or annotation layer for epitope outputs
- –Workflow value depends on downstream Poisson–Boltzmann tooling integration

HDExaminer
vertical specialistHDX-MS analysis software maps protein structural changes and supports antibody-antigen epitope studies.
Guided mapping evidence consolidation that ties assay results to residue and interface context for direct antibody comparisons.
HDExaminer is built around linking epitope evidence to residue and interface context rather than running only raw assay analytics. It supports epitope binning style interpretation patterns and residue-level summaries that match typical antibody panel design workflows. Structural inputs such as PDB models are used to anchor mapped residues for antibody–antigen complex visualization. Automation is largely workflow-driven, with less emphasis on writing custom analysis code inside the interface.
A key tradeoff is that HDExaminer fits best when structural reference data is available and when mapping questions stay within its supported evidence types. Teams doing purely B-cell epitope prediction from sequence alone without structural grounding may need additional tools for upstream preprocessing. It is a practical choice for groups that want consistent interpretation across multiple antibodies in parallel and produce shareable mapping outputs for handoff.
- +Residue-level epitope residue annotation tied to interface context
- +Structure-anchored mapping views for antibody–antigen complex visualization
- +Evidence organization across multiple antibodies for comparison
- +Exportable mapping summaries for downstream reporting pipelines
- –Best results depend on having structural reference inputs
- –Limited room for custom computation when evidence types differ
- –Workflow configuration needs time for consistent team usage
- –Automation is more guided than API-driven customization

Best for: Fits when teams map antibody epitopes with structural grounding and need repeatable residue-level evidence comparisons.
ClusPro
vertical specialistProtein-protein docking server with antibody-antigen mode for conformational epitope identification.
Docking pose clustering that concentrates predicted contact regions into interpretable interface groups.
ClusPro takes PDB structure input for antibody and antigen models and produces clustered docking solutions that make it easier to compare recurring contact regions across top-scoring groups. The output emphasizes antibody–antigen interface interpretation by highlighting residues in predicted contact regions and by organizing poses into clusters for downstream evaluation. This fit is strongest for conformational epitope mapping because the signal comes from three-dimensional docking geometry.
A tradeoff is that ClusPro depends on structural docking inputs, so it does not replace peptide tiling, alanine scanning, or alanine scanning workflows that start from synthesized variants. It is a good usage situation for teams that need a fast structural hypothesis for epitope binning or competition assay planning before committing to more data-heavy validation.
- +Docking pose clustering makes interface comparisons faster
- +Structure-based mapping supports conformational epitope hypotheses
- +Residue-level interface highlights support epitope annotation
- +Ranked model sets support rapid candidate selection
- –Requires antibody–antigen structures for meaningful predictions

The software emphasizes repeatable analysis runs with configurable mapping logic and exportable outputs for downstream reporting. Its fit is strongest when epitope mapping needs to connect sequence residue positions to structural interfaces without manual relabeling.
- +Residue annotation links mapping results to interface context during review
- +Configurable analysis runs reduce rework across antibody panel iterations
- +Exportable mapping outputs support downstream immunoassay and reporting workflows
- +Workflow-oriented visualization accelerates inspection of candidate epitope regions
- –Discontinuous and conformational epitope mapping coverage depends on available structural inputs
- –Setup and configuration discipline is needed to keep residue numbering consistent across sources
- –Automation depth is thinner for fully programmatic, large batch tiling workflows
- –Limited evidence-style provenance controls for multi-step mapping pipelines
Best for: Fits when teams need residue-level epitope mapping tied to structural interfaces for antibody panel review.

- –Throughput is limited by docking plus refinement runtime per pose
Best for: Fits when structure-based epitope mapping needs flexible-peptide docking and residue prioritization for validation experiments.
PEP-FOLD
vertical specialistDe novo peptide structure prediction tool for linear epitope modeling from amino acid sequences.
Dedicated peptide structure modeling workflow that turns epitope-fragment sequences into usable 3D conformations.
PEP-FOLD generates peptide structures from sequence and supports epitope mapping workflows built around peptide tiling and residue-level interpretation. The core distinction is its dedicated peptide structure modeling pipeline for short sequences, which can be fed into downstream antibody–antigen interaction analysis.
It is generally used when conformational hypotheses for linear fragments matter more than when full antibody–antigen complex modeling is required. In practice, it supports structure-aware annotation of predicted epitope residues and visualization of modeled peptide conformations that can be compared across variants.

How to Choose the Right epitope mapping software
Epitope mapping software turns antigen and antibody assay inputs into residue-level hypotheses that can be compared across antibody candidates and antigen variants. This guide covers PDB2PQR for Poisson–Boltzmann-ready electrostatics preprocessing, HDExaminer for structure-anchored residue evidence consolidation, and tools for structure-driven conformational and linear mapping across BioLuminate, ClusPro, and iVAX.
Across these options, the practical differences show up in how each tool connects residue annotation to a specific interface context, how repeatable outputs are for panel-scale re-runs, and how much automation and workflow control exists for integrating external experiment datasets. The coverage also spans non-antibody-complex workflows like Rosetta FlexPepDock and PEP-FOLD for peptide conformational sampling, plus evidence-focused analysis via IEDB Analysis Resource.
Epitope mapping software for residue-level antibody–antigen interface hypotheses
Epitope mapping software generates residue-level epitope regions from peptide tiling, assay evidence, or structure-driven docking, then ties those residues to interaction context for antibody comparison. Tools like HDExaminer consolidate assay evidence into residue annotation linked to interface context, which supports direct antibody comparisons from the same structural reference.
In structure-centered workflows, some tools focus on upstream model preparation for electrostatics-driven interface interpretation, while others focus on interface hypothesis generation from docking poses. PDB2PQR automates deterministic PDB to PQR conversion with consistent atom typing and parameter assignment for Poisson–Boltzmann solvers, while ClusPro clusters docking poses into interface groups that concentrate predicted contact regions for conformational epitope mapping hypotheses.
Key epitope-mapping capabilities to compare across tools
Residue-level epitope mapping only becomes useful for antibody comparison when the tool ties mapped residues to the right structural or assay context. This guide focuses on features that preserve residue identity across inputs and keep mapping outputs interpretable at the interface level.
The biggest practical differences show up in how each tool generates or refines models, how repeatable the residue mapping is for panel re-runs, and how much automation exists when external assay datasets must be linked to residue annotations.
Input-to-residue repeatability for interface-linked outputs
PDB2PQR generates deterministic PDB-to-PQR model inputs with automated atom typing and parameter assignment for reproducible Poisson–Boltzmann runs. BioLuminate provides structure-aware residue annotation that ties mapped residues to interaction context during interface review.
Evidence consolidation that stays attached to residues and interface context
HDExaminer consolidates assay evidence into residue annotation linked to interface context so residue-level antibody comparisons remain consistent. IEDB Analysis Resource connects residue-level epitope views to curated IEDB evidence and annotation context for evidence-grounded mapping.
Conformational epitope hypothesis generation from docking or flexible peptide models
ClusPro clusters docking poses into interpretable interface groups that concentrate predicted contact regions for conformational epitope mapping hypotheses. Rosetta FlexPepDock performs explicit peptide conformational sampling during refinement to infer residue-level interfaces from a single complex model.
Peptide-centered workflows for fragment and tiling-based residue annotation
iVAX runs batch-configured peptide tiling to produce residue-level epitope annotations with consistent re-runs across antigen sets. PEP-FOLD provides a dedicated peptide structure modeling workflow that turns epitope-fragment sequences into usable 3D conformations.
Annotation and visualization coupling inside a single analysis workspace
BIOVIA Discovery Studio couples epitope residue annotation to antibody–antigen complex visualization in the same analysis workspace. HDExaminer also supports structure-anchored mapping views for antibody–antigen complex visualization, but it centers on evidence consolidation.
How to choose epitope mapping software for antibody discovery workflows
The first decision fork is whether mapping output must be structure-grounded through electrostatics or docking pose interfaces. Tools like PDB2PQR and ClusPro are designed to feed structure-based interpretation, while iVAX and PEP-FOLD focus on peptide tiling and peptide conformations for residue interpretation.
The second decision fork is how evidence enters the workflow. HDExaminer and IEDB Analysis Resource emphasize evidence consolidation into residue annotations, while BioLuminate and BIOVIA Discovery Studio emphasize structure-linked review and residue annotation tied to interface visualization.
Choose structure-driven preprocessing or skip straight to mapping refinement
If Poisson–Boltzmann solvers must run on consistent electrostatics inputs, PDB2PQR automates deterministic PDB-to-PQR conversion with automated atom typing and parameter assignment. If conformational hypotheses must start from docking pose ensembles, ClusPro clusters docking poses into interface groups for faster interface comparisons.
Decide whether evidence consolidation is a first-class workflow input
If assays already exist and residue-level mappings must be tied to interface context for direct antibody comparisons, select HDExaminer for residue annotation linked to interface context. If curated experimental annotations must be the backbone for residue-level views, select IEDB Analysis Resource to link mapped regions to IEDB evidence and annotation context.
Pick a conformational strategy based on what model flexibility is needed
If interface structure emerges from docking pose variation across conformations, use ClusPro because pose clustering concentrates predicted contacts into interface groups. If peptide flexibility must be sampled explicitly during refinement, use Rosetta FlexPepDock because it produces peptide pose ensembles with explicit peptide flexibility.
Match your mapping modality to your peptide handling requirements
If the workflow starts with overlapping peptide tiling across antigen sets, use iVAX because it batch-configures peptide tiling and produces residue-level annotations for repeatable re-runs. If fragment sequences require 3D peptide conformations before residue interpretation, use PEP-FOLD since it models epitope-fragment sequences into usable 3D conformations.
Plan for residue numbering consistency when multiple sources are involved
If residue numbering must stay consistent across sources and runs, BioLuminate requires setup and configuration discipline to keep residue numbering aligned between structural inputs. If the workflow starts with electrostatics preprocessing inputs, PDB2PQR makes deterministic atom typing and parameter assignment part of the pipeline to reduce model input drift.
Who benefits from these epitope mapping software capabilities
Teams gain the most when their epitope mapping pipeline has a clear residue-level output target tied to interface context or evidence context. The right tool set depends on whether work is centered on structure-based interface hypotheses, evidence consolidation, or peptide tiling and peptide conformation modeling.
These profiles also reflect operational needs like repeatability for panel-scale re-runs and constraints around how much customization is required to connect external data to residue annotations.

Other failures come from inconsistent residue identity. Residue numbering drift across structural sources or inconsistent mapping modalities can break residue traceability across iterations, which undermines antibody panel comparisons.
Using a structure-dependent conformational workflow without reliable antibody–antigen complex inputs
ClusPro requires antibody–antigen structures for meaningful conformational epitope mapping predictions, and best results depend on careful input preparation and cleanup.
Assuming an electrostatics preprocessing utility includes epitope mapping features
PDB2PQR focuses on deterministic PDB-to-PQR conversion and automated atom typing for Poisson–Boltzmann runs, while it provides no built-in epitope mapping, residue ranking, or epitope binning.
Treating peptide tiling tools as full conformational or discontinuous epitope solutions
iVAX is tuned for repeatable linear epitope mapping via batch peptide tiling, and it has weaker fit for conformational and discontinuous epitope mapping workflows.
Building residue-level comparisons when structural inputs use inconsistent residue numbering
BioLuminate can require setup and configuration discipline to keep residue numbering consistent across sources, which matters for residue-level epitope annotation tied to interface context.
Expecting evidence consolidation without providing structure-linked reference inputs
HDExaminer depends on having structural reference inputs for best results, because it ties residue annotation to interface context for structure-anchored mapping views.
