Can I convert multiple PDB files to SIX at once?

Yes, batch conversion is supported: you can upload multiple PDB files and produce individual SIX outputs or a single aggregated SIX package. For best results, ensure files have consistent metadata and consider zipping archives for upload to streamline the process.

What is the maximum file size for PDB to SIX conversion?

Free users can convert files up to 250MB, premium users up to 1GB; these limits cover single-file uploads per conversion. For larger datasets, split files or contact support for bulk processing options and custom arrangements.

Is my PDB file secure during conversion?

Yes, conversions are handled over encrypted connections and temporary files are deleted after processing to protect your data. For sensitive or proprietary structures, use premium or enterprise workflows that offer extended retention policies and private processing environments.

What is PDB to SIX Conversion?

PDB to SIX conversion is the process of transforming a PDB (Protein Data Bank or Palm Database) file into the SIX format, creating a SIX document that packages structural, annotation, or record data in the SIX container specification. This conversion re-maps the original PDB content and metadata into SIX’s file structures so software that reads SIX can access molecular or database records without losing key information.

Image

PDB files usually use the MIME type chemical/x-pdb and store detailed structural data for molecular models. SIX files have a MIME type of application/x-six and are designed for efficient data compression and fast rendering. Codecs used for SIX format support enhanced visualization features in compatible software.

Benefits of Converting PDB to SIX

✓Preserve complex PDB metadata in a standardized SIX container for easier sharing.
✓Reduce storage and transfer overhead with optional SIX compression settings.
✓Maintain coordinate precision by selecting lossless SIX export when needed.
✓Streamline workflows by converting multiple PDB files into a single SIX package.
✓Improve compatibility with SIX-enabled tools for visualization and archiving.

PDB vs SIX Comparison

PDB files are typically used as protein structure data files, containing atomic coordinates and metadata. SIX files are a specialized format that offers optimized storage and enhanced compatibility with certain molecular visualization tools. While PDB is widely supported, SIX provides advantages in file size and loading times.

Supported PDB Input Formats

1PDB input variations:
2- Standard PDB (.pdb) files from the Protein Data Bank containing atomic coordinates and metadata
3- mmCIF-derived PDB exports (.cif exported as .pdb)
4- Palm Database PDB variants (legacy .pdb files used by older PalmOS apps)
5- Compressed PDB inputs (.pdb.zip, .pdb.gz) — upload after decompression or use integrated decompression if supported
6SIX output options:
7- Uncompressed SIX container (.six) preserving original precision and metadata
8- Compressed SIX (.six.zip) for smaller transfer sizes
9- Quality tiers for SIX: high (lossless metadata and coordinate precision), balanced (minor precision rounding to reduce size), and compact (max compression, reduced precision)

Tips & Limits for PDB to SIX Conversion

Keep individual PDB files under 100–200 MB for fastest processing; very large structure files (>500 MB) can slow conversion and may require chunking.

To preserve scientific accuracy, use the high-quality/lossless SIX option and avoid rounding coordinates unless you need smaller files.

For many files, batch conversion saves time—prepare PDB files with consistent headers and metadata to ensure uniform mapping into SIX containers.

Some PDB variants (legacy PalmOS .pdb) lack scientific headers; verify and add missing metadata before converting to avoid incomplete SIX records.

Frequently Asked Questions

What is the best way to convert PDB to SIX?▼

The best approach is to choose a converter that supports PDB header and REMARK fields and offers precision control for coordinates. Select a lossless or high-quality SIX export to preserve scientific data, and validate the resulting SIX file in a SIX-capable viewer to ensure metadata mapped correctly.

Is PDB to SIX conversion free?▼

Yes, ConvertFiles offers free PDB to SIX conversion for standard usage tiers, allowing basic conversions without charge. There may be limits on file size or batch volume for free users, with paid plans providing larger limits and faster processing.

Will I lose quality converting PDB to SIX?▼

Not if you choose a lossless or high-quality conversion setting—these preserve full coordinate precision and metadata. Lower or compact quality settings may round coordinates or drop nonessential comments to reduce file size, so choose based on your accuracy requirements.

How long does PDB to SIX conversion take?▼

Small PDB files (a few MB) typically convert in seconds to under a minute, while large structures (hundreds of MB) can take several minutes depending on server load and compression settings. Batch jobs and high-compression exports add processing time, so expect longer durations for many or very large files.
