## 1.0 SUMMARY

Convert raw swissprot:PDB equivalence file to EMBL-like format. Convert swissprot:PDB codes file to EMBL-like format

## 2.0 INPUTS & OUTPUTS

PDBTOSP parses the swissprot:PDB equivalence table available at http://www.expasy.ch/cgi-bin/lists?pdbtosp.txt and writes the data out in EMBL-like format. The raw (input) file can be obtained by doing a "save as ... text format" from the web page. No changes are made to the data other than changing the format in which it is held. The input and output files are specified by the user.

## 3.0 INPUT FILE FORMAT

An excerpt from the raw swissprot:PDB equivalence file is shown (Figure 1).

## 7.0 KNOWN BUGS & WARNINGS

None.

## 8.0 NOTES

PDBTOSP is used to create the EMBOSS data file Epdbtosp.dat that is included in the EMBOSS distribution.

### 8.1 GLOSSARY OF FILE TYPES

FILE TYPE | FORMAT | DESCRIPTION | CREATED BY | SEE ALSO
swissprot:PDB equivalence file | EMBL-like format. | A file containing swissprot identifiers for PDB codes. | Included in the EMBOSS distribution | N.A.

None

## 9.0 DESCRIPTION

Some research applications require knowledge of the database sequence(s) that corresponds to the sequence(s) given in a PDB file. A 'swissprot:PDB equivalence' file listing accession numbers and swissprot database identifiers for certain PDB codes is available, but is not in a format that is consistent with flat file formats used for protein structural data in emboss. PDBTOSP parses the swissprot:PDB equivalence in its raw format and converts it to an EMBL-like format.

## 10.0 ALGORITHM

PDBTOSP relies on finding a line beginning with '____ _' in the input file (all lines up to and including this one are ignored). Lines of code data are then parsed, up until the first blank line.
