How to programatically get the FTP URL, given a MassIVE identifier #28

Closed wfondrie closed 6 months ago

wfondrie commented 6 months ago

Hi folks 👋

Recent changes to the MassIVE FTP site organization broke the functionality of my project, ppx (https://github.com/wfondrie/ppx/issues/30), which strives to make it easy to programmatically access datasets. It seems that projects are now distributed among multiple version subdirectories (currently, I see v0[1-7] and x01).

Is there an API endpoint or similar from which I can retrieve the correct FTP URL for a given dataset? I spot checked a few using the PROXY API (http://massive.ucsd.edu/ProteoSAFe/proxi/v0.1/datasets/<accession>), but they were incorrect.

For example:

https://massive.ucsd.edu/ProteoSAFe/proxi/v0.1/datasets/MSV000094236

Returns an FTP link of ftp://massive.ucsd.edu/MSV000094236 when it is actually ftp://massive.ucsd.edu/v07/MSV000094236.

Thanks!

Thanks for letting us know about this. I know this restructuring has been an inconvenience, and I appreciate your patience with this.

The PROXI /datasets API endpoint should be showing the correct FTP URL. This is a bug that I will fix ASAP. Thank you for bringing this to our attention.

@wfondrie This issue is now resolved. The example you provided now returns the correct FTP URL:

https://massive.ucsd.edu/ProteoSAFe/proxi/v0.1/datasets/MSV000094236

Please let me know if you see any other issues.
