Hi Frank,

I am trying to do some lesion quantification and am getting a strange segmentation fault with a dsi studio command. Would you happen to know what this error could be referring to?

sh: line 1: 98746 Segmentation fault: 11 /Users/rahuja6/Library/R/x86_64/4.2/library/LQT/extdata/DSI_studio/dsi_studio.app/Contents/MacOS/dsi_studio --action=ana --source=/Users/rahuja6/Library/R/x86_64/4.2/library/LQT/extdata/Tractography_Atlas/HCP842_1mm.fib.gz --tract=/Users/rahuja6/Library/R/x86_64/4.2/library/LQT/extdata/Tractography_Atlas/All_Tracts/SCP.trk.gz --roi=/Users/rahuja6/Library/R/x86_64/4.2/library/LQT/extdata/Example_Lesions/ExampleLesion1.nii.gz --output=/Users/rahuja6/Desktop/Results/ExampleLesion1/Tract_Disconnection --export=stat

Thank you!

Rohil

Hi Rohil,

    Sorry about the problem.
    Could you post the command line output before the segmentation fault?

Best regards,
Frank

Hi Rohil,

Any chance you remember what solved the issue for you? I'm running into segfaults at a similar step using LQT.

Thanks!

Hi Alex,

I had used a different version of DSI Studio to solve the problem, and had also gone from trying to use the R version of LQT to the Matlab version of LQT. I used the DSI Studio release that is included in the box of the matlab toolkit, and that solved the problem for me. 

Hope that helps!

Best,

Rohil
