Just want to ask is there a version of fmriprep that is still compatible with Singularity 2.4.6? I tried running the latest version of fmriprep (1.5.6) but encountered an error of ‘Unknown image type’, I also tried some older versions fmriprep (1.0.11) and got the same error.
I know that this isn’t the answer that you want, but there are some fairly significant security issues with 2.4.6, and minimally you (or a sysadmin) should consider upgrading to 2.5.1. Better yet, update to some 3.x version to likely fix this error too
