External Email - Use Caution
Dear Freesurfer Developers,
First of all, thank you for the fantastic work on the Histo Atlas
Segmentation tool and the amazing updates in FreeSurfer 8!
Since I encountered some crashes
with mri_histo_atlas_segment_fireants and mri_histo_atlas_segment_fast, I
wanted to share the issues I experienced.
I downloaded FreeSurfer 8 to my M1 MacBook Pro using the installation
package, but it partially contains an older code version compared to the
one on GitHub for the NextBrain segmentation with FireAnts. For example, it
attempts to import FireAnts packages that are not included, such
as GreedyRegistration from fireants.registration. I then installed
FreeSurfer 8 directly from GitHub, which worked. However, as soon as
EasyReg started, I encountered a thread lock. This also occurred when
trying to run the EasyReg step directly as a terminal command.
After that, I attempted the installation on Linux. However, in the latest
installation package for Ubuntu 18, the ERC_bayesian_segmentation folder
was completely missing. I then installed it again directly from GitHub but
ran into a similar issue with EasyReg during
the mri_histo_atlas_segment_fireants process, even when using only a single
thread.
I also tried mri_histo_atlas_segment_fast because my data is 1mm isotropic.
However, this also did not work, as it failed when starting the
registration with SynthMorph. I was able to resolve this by using
the spawn method for multiprocessing, preventing issues when processing
both hemispheres simultaneously.
Additionally, I noticed that mri_TumorSynth is missing, although it is
listed on the FreeSurfer wiki page. I hope it will be available in an
updated version of FreeSurfer 8.
Thanks in advance!
Best regards,
