Dwi_legacy_gpu command erroring out using QuNex version v0.97.3 with eddy_cuda10.2

Hi QuNex Team,

I am running the dwi_legacy_gpu command using QuNex version v0.97.3. I encountered an error with eddy_cuda10.2, error stack trace is provided below. I am unable to decipher the error log.

I have updated the default CUDA version to 10.2 as I have encountered an issue with 10.1 /opt/qunex/bash/qx_utilities/dwi_legacy_gpu.sh: line 565: /opt/fsl/fsl/bin/eddy_cuda10.1: No such file or directory

Could you please assist me in resolving this issue? I have attached the complete log output of the dwi_legacy_gpu command below. Let me know if you need any more information. Thanks in advance.

Thanks

Hi there,

CUDA 10.2 and above support is currently functional only for the hcp_diffusion command. Next version (to be released in a week or so) will add this support to the whole DWI pipelines. The testing of the next release is in its final phase, so things are looking good for a release by the end of May.

Hi Jure,

Thank you for the update. I am looking forward to the release.

Thanks,
