Remove b-values from analysis

Dear all,

I’m converting my data to bids using dcm2bids and processing it using qsiprep. My data consists on 6 b0, 3 b200, 8 b500, 64 b1000 and 64b2000. I was wondering if it is possible to remove the b200 from the analysis, but at the conversion stage, so the json file is consistent. Is that possible? Thanks in advance.

Best regards,


I think the only thing you could do at the conversion step is to remove the dicoms corresponding to b-Val’s you want to remove. Dcm2bids doesn’t have a filter for it as far as I know. However I think if you were to convert as normal and then use a tool like MrTrix dwiextract before preprocessing to get only certain dwi shells, it would work fine.
