Ubuntu 22.04 LTS installation

[Luis Alvarado]

Hi Frank,

Is there a way to run DSI Studio on ubuntu 22.04? I tried the complied version for 20.04 (dsi_studio_ubuntu_2004.zip) without success. I get the following errors:

Inconsistency detected by ld.so: dl-call-libc-early-init.c: 37: _dl_call_libc_early_init: Assertion `sym != NULL' failed!

Best,

Luis

I will see if I can work out the 22.04 version.

Hi Luis,

    

    I compiled the 22.04 version at https://dsi-studio.labsolver.org/download.html  The app bundle does not work yet on 22.04, and thus the executive may show library related problems. If that happens, you may either install Qt6 using the command listed at https://github.com/frankyeh/DSI-Studio/blob/master/build_packages/ubuntu_2204/Dockerfile, or compile DSI Studio using the same steps listed in the Docker file.

    Please note that this version has a different "QA" replaced by nQA. The newly created FIB files will be different from the FIB files created by version before August 2022.

Best regards,

Frank

Hi Frank,

Our lab server had to be updated to Ubuntu 22.04 and I am having a feel issues with the latest DSI Studio version for Ubuntu 22.04 that I downloaded from the website. We oftentimes use DSI Studio for 3D rendering of T1 images and corregistered-CTs with electrodes so we load the .nii.gz files straight in "step 3 fiber tracking" (selecting "see all image files"), however, when I load those images on this 22.04 version of ubuntu, they look binarized and I cannot set the max voxel intensity window above 2.0, while the T1 images have voxel intensities of over 1000s.  This was never a problem on the Ubuntu 20.04 version. Also, I used to get a "need alignment?" popup when I loaded the corregistered-CT so I could chose "no", however, now it is doing the alignment without asking. Is it possible to have those things fixed in 22.04 version?  

Thank you,

Dan

Hi Dan,

    I fixed the issues. The voxel intensity will be normalized to [0 1] after loading.

    For the registration problem. In the new version, DSI Studio will check if the file name contains "reg", if yes and the image dimension is the same as the T1W, it will not initiate registration.

    The new build is undergoing at: https://github.com/frankyeh/DSI-Studio/actions/runs/4304736360

    Thanks for reporting the problem.

Best regards,

Frank
