# Correlations fail for at least some ProbeSet datasets (as the target dataset)

## How to reproduce

- https://genenetwork.org/show_trait?trait_id=P40630_SWEEQMAEVGR_2&dataset=EPFL-ETHZ-BXD-LivProtCD-HF-1119
- Use the default dataset for correlation (the same as the trait)
- You should get the following error:

GeneNetwork tux01:gene:2.11-rc2-gn_20221013-4eb4beafd 
    [Errno 2] No such file or directory: '/home/gn2/production/tmp/gn2/gn2/ProbeSetFreezeId_886_EPFL/ETHZ BXD Liver Proteome CD-HFD (Nov19)' (error)
    
This obviously has something to do with the sample data files, though not sure what yet.
