Guidelines 243: The protein sequence database used including the exact version/date of download (if a release version is not available) are described

[viikiid]

The description of that guideline does not really make sense to me:
"If the original FASTA file from the resource is not transform/change and the release number of the file is not available; the exact version/date of the downloaded FASTA file should be provided."

Do you want to say, that the original file should not be changed? Or do you want to say, that either the release version or an exact download date should be provided? Or both?

Hi @viikiid What we tried to say is

• Name the sequence database
• Reference the version
• If there is no version, state when it was downloaded

Any ideas how to better phrase this?

Maybe you should just say it exactly like that (your bullet points are clear to me)

Here's an updated suggestion:

Name: The used protein sequence database must be unambiguously referenced 
Category: Bronze    
Description: During the protein identification step, the spectrum identification search engine algorithm
commonly uses a  protein sequence FASTA database from public resources (e.g. ENSEMBL, Uniprot). 
The source of the database including the exact version must be named. If a version is not available, 
the date of download must be reported instead. This is **only** applicable to cases where the original 
sequence database was **not modified** (ie, no variants added, etc).
