Naming of multiple pairs of spin echo fieldmaps

Hello,

I’ve got data from a subject with 2 pairs of spin echo fieldmaps; each pair is intended for different functional data, so I need to ensure that both pairs are converted. Would this be the proper way to name them?

sub-01_dir-AP_run-01_epi.json
sub-01_dir-AP_run-01_epi.nii.gz
sub-01_dir-AP_run-02_epi.json
sub-01_dir-AP_run-02_epi.nii.gz
sub-01_dir-PA_run-01_epi.json
sub-01_dir-PA_run-01_epi.nii.gz
sub-01_dir-PA_run-02_epi.json
sub-01_dir-PA_run-02_epi.nii.gz

The only other way I could imagine naming the files is having the runs range from 01-04; however, the convention above passes BIDS validation, so I’m inclined to go with this, but I wanted to double check before proceeding.

Thanks

This looks reasonable to me.
