How to find correspondence between GSM and all SRA identifiers (SRR DRR ERR) ?

Question

[Helen]

Hello,

The file SRA_Accessions.tab helped me to extract the SRR to GSM mapping but what about the DRR and ERR codes? According to what I checked, it does not contain ERR accession codes. I found some DRR codes but regardless of particular GSM code.

Is there another file that contains DRR or ERR codes?

Thanks in advance

You asked that already: What is the difference between SRR, DRR, ERR ?

Please do not double post.

Hello Helen,

most of the time the three databases synchronize the reads, and it's quite a rare to have a situation when there's a SRR but no DRR/ERR.

I have had the same issue too.

I think Helen means that the specified file (SRA_Accessions.tab) which is useful for finding SRR accession codes for GEO accession codes doesn't seem to contain any ERR codes, and the DRR codes it does contain don't seem to have proper GEO codes. Hence if I have a list of GEO accession codes and I write a script to get their corresponding SRA codes, I would only find the ones that correspond to SRR codes and not to ERR or DRR.
