Qsiprep --recon-only: dsi_studio_gqi works but mrtrix_singleshell_ss3t_ACT-hsvs fails

Summary of what happened:

Hi All. I’m having trouble getting the mrtrix_singleshell_ss3t_ACT-hsvs reconstruction to run.

  1. Ran fmriprep on T1w and rs-func data, which generated sourcedata/freesurfer directory with subject sub-directories.

  2. Ran qsiprep preprocessing on single dwi/dti scan using singularity container, version v0.21.4 with cuda variant of eddy.

  3. Then attempted reconstruction (qsiprep --recon-only) with the mrtrix_singleshell_ss3t_ACT-hsvs workflow. As the software constructs the processing pipeline, before any actual computation, I get the following error:

Exception: Trying to connect anat_ingress_wf.register_fs_to_qsiprep_wf:outputnode.brain to anat_ingress_wf.outputnode:brain but input ‘brain’ of node ‘anat_ingress_wf.outputnode’ is already

Any help would be very much appreciated!

Screenshots / relevant information:

  • The warning that about a non-gzipped sub-AGWBAT_desc-preproc_T1w.nii (apparently the preprocessing stage did not compress that particular file) goes away if I manually zip the file, but the results are the same.

An alternative workflow, dsi_studio_gqi, runs to completion.

The (external) bids validation doesn’t like the old fashioned way of naming the reverse phase encoded B0 in fmap (but it was the only way I could get the qsiprep preprocessing to run; the software doesn’t seem to have been updated to use the newer bids conventions). I don’t think this is an issue in the reconstruction phase.

Should I be using the latest release (0.21.4 at this time)? The docker installation instructions on readthedocs.io seem to say yes, but it’s not advised for singularity? The latest version listed on readthedocs.io (“Whats new”) is v0.19.0. Clearly, I’m a little confused.

Hi @silophophe,

This is an ongoing issue discussed here Error in connecting qsirecon nodes (0.20.1dev) · Issue #718 · PennLINC/qsiprep · GitHub. You can use QSIRecon with 0.19.1 in meantime.


Thanks Steven. I’d been googling the past couple of days and didn’t come across this for some reason. Sorry for the redundancy. And thanks for the alternative.

On a potentially related subject: I ran fmriprep 23.2.2 on my fmri scans, which runs freesurfer 7. It looks like the qsiprep singularity container bundles freesurfer 6. Can qsiprep recon use the segmentations from freesurfer 7?

Yes it should work with FS7.

Thank you.

I bumped the entire qsiprep processing down to 0.19.1 in an effort to remain consistent across preprocessing and reconstruction. However, when using 0.19.1 for preprocessing, the eddy_cuda segment throws an error: “eddy_cuda: error while loading shared libraries: libcublas.so.10: cannot open shared object file: No such file or directory”. I found a thread [1] discussing a similar problem, which relates to a missing NVIDIA Container Toolkit. I searched the various modules we have installed on our cluster but did not find anything that fit that description.

In your opinion, since preprocessing and reconstruction are relatively decoupled, do you think it’s defensible to use qsiprep 0.21.4 for preprocessing and version 0.19.1 for reconstruction?

1: Qsiprep wirh cuda 12.2 - #5 by Ralf

Yes, that should be fine

I agree- it’s totally fine to mix versions for preprocessing and recon. In fact, we will be splitting these two pipelines into two software packages, qsiprep and qsipost.

We’re continually running into issues where updating a software packages fixes a preprocessing bug, but breaks a recon workflow. Our group is currently also using 0.21.4 for preprocessing and 0.19.1 for recon

Thanks, Matt, for the affirmation.

Reconstruction with 0.19.1 ran fine after I compressed the one file qsiprep/sub-AGWBAT/anat/sub-AGWBAT_desc-preproc_T1w.nii that came out of the 0.21.4 preprocessing pipeline as naked nifiti (i.e., not compressed with gzip).

Thank you all for your help!
