An explanation of the fields and options in the CHOP submission page:

 

Sequence format Default: simple sequence or fasta formatted sequence
SWISS-PROT ID: Identifier from SWISS-PROT database, usually in the format of NAME_ORGANISM
More format options coming soon.. (PDB, TrEMBL, ...)
Output format TEXT: standard TXT (ASCII) format that can be displayed in any text editor
HTML:pretty output optimized for web browsers
BLAST E-value The e-value threshold when the query is searched against PrISM domains or SWISS-PROT database using BLAST, default=0.01
HMMER E-value The e-value threshold when the query is searched against Pfam-A database using HMMER, default=0.01
Min domain coverage CHOP requires the homologous region between the query protein and the known domain in the database to cover at least certain percentage of the known domain, default=80
Min length of domain The minimum length of the fragment CHOP considers and reports as a domain, we recommend the value to be larger than 30
