PDB to FTS conversion is the process of transforming a file in Protein Data Bank (PDB) format — a plain text format that describes 3D coordinates, atoms, residues, and metadata for macromolecular structures — into an FTS (Flexible Table Structure) file used for compact, queryable structural or tabular representations. This conversion reorganizes PDB coordinate and annotation data into FTS’s table-like schema to enable faster searching, indexing, or integration with downstream analysis tools.

PDB files usually have the MIME type application/x-pdb and are used primarily for structured data storage in various software environments. FTS files, often with MIME type application/x-fts, are designed to store full-text search indexes and support faster querying. Codecs for PDB vary depending on the software source, whereas FTS formats commonly use indexing algorithms optimized for quick text retrieval.
The FTS (.FTS) format is commonly used for document. Understanding its characteristics can be helpful when converting to or from other formats like PDB.
While specific technical details aren't available here, FTS files generally serve the purpose of storing document effectively within their domain.
Our Online PDB to FTS Converter provides a seamless way to convert your PDB files into FTS format without installing any software. Designed for efficiency and simplicity, this tool helps users transform their documents quickly while preserving quality. Whether you are working in documentation, software development, or data management, converting PDB to FTS online has never been easier.
PDB files typically store structured document databases, while FTS files are optimized for full-text search indexing and faster retrieval. Converting PDB to FTS allows easier searching and management of large document collections. While PDB is more focused on data containment, FTS offers enhanced text search capabilities.
Keep individual PDB files under 100 MB for optimal browser-based conversion; server tools handle larger files but may be slower.
To preserve structural detail, enable at least 3 decimal places of coordinate precision and include B-factor and occupancy fields in the FTS schema.
For large datasets, use batch conversion with compressed input (e.g., .pdb.gz) and output compression (.fts.gz) to reduce transfer time and storage.
Be aware that PDB is record-based text with possible nonstandard annotations; automated converters may drop custom REMARKs or uncommon record types unless explicitly preserved.
