🐞 Bug Report: GNPS 2 Metadata Parsing in FBMN Fails Despite Valid Format

[Michaela Plechatá]

  Hello everyone,

Metadata file that works correctly in GNPS Classic fails in GNPS 2. During a Feature-Based Molecular Networking (FBMN) run, the metadata is misinterpreted and renders column headers incorrectly, producing labels like:  ATTRIBUTE_MEDIA:GNPSGROUP:ISP3 

Instead of recognizing standard ATTRIBUTE_* columns. 
I did this: Prepared a tab-separated metadata file (TSV)

Column headers follow the format:

filename, ATTRIBUTE_EXTRACTION, ATTRIBUTE_MEDIA, ATTRIBUTE_STRAIN

Values contain only alphanumeric characters (e.g., mcx2, isp7, etc.)

Uploaded to GNPS 2 and linked to an FBMN job

  The same metadata works perfectly in GNPS Classic FBMN.

Does anyone know what to do? 
Thanks  
 Misa

Hi Misa,

I htink the two steps forward - 

1. can you show upload the metadata, GNPS1 and GNPS2 jobs

2. stop by my office hours
