External Email - Use Caution With the .deb and .rpm installers on Linux, you can optionally apt/yum remove freesurfer to delete the old release prior to installing a new release.  A new release will be installed in a subdirectory named after the (different) release version so there will be no overlap of files.  Or 7.4.1 is installed as /usr/local/freesurfer/7.4.1 and 8.0.0-beta is installed as /usr/local/freesurfer/8.0.0-beta.  You may get run time errors if you don't use those installers. - R.

For what it’s worth, we moved to Beta version 8 and after setting export FS_ALLOW_DEEP=1 it seems to be running fine now. Noah is running it now and it will take several hours to finish before we know if it works 100% for what they want. I installed it the exact same way I did 7.4.1; short of a bug in 7.4.1 or a configuration issue either in the OS or something possibly being cached from a prior install I’m not sure what else to look into.

Appropriate image for texture/intensity based analysis

External Email - Use Caution We want to perform appearance-based analysis that also takes advantage of automated outputs, especially segmentations. For this, we have considered different options: raw image, orig.mgz, norm.mgz, T1.mgz, in addition to whether to use base or long pipeline images. There are competing considerations of some intensity normalization being helpful, and at the same time avoiding heavy pre-processing. Are there any recommendations from folks who might have done analysis like this ?

External Email - Use Caution If you downloaded the latest dev build from,https://secure-web.cisco.com/1rfGZf44C3EnYEUAAH8Ai3U46OACeadGiVwnMr-cm… after November 2nd, then you are essentially running the 8.0.0-beta release of freesurfer (and not the 7.4.1 release).    I don’t have a workaround for running the new recon-all setup in 8.0.0 on a machine with 16GB total memory to run both the OS and applications.  Because the new setup requires more RAM, we changed the requirement for recon-all in 8.0.0 to 24G+ on the download page,https://secure-web.cisco.com/1mBwwT4rr7KHkRtYHaU4jk9QZ4F3_X1jonJcs-sVO… management and swapping out to disk for virtual RAM is only going to get you so far with 16GB of physical RAM even with no other applications running on the machine. You could try reverting the 8.0.0-beta or a dev build from after Nov. 2nd to the less memory intensive behavior by exporting the environment variable FS_V8_XOPTS=0 on the recon-all command line.  Alternately, you could download and install a stable pre-8.0.0 dev build from the URL below (more recent than 7.4.1 but pre-dating the 8.0.0-beta).https://secure-web.cisco.com/1QPq8tBaOQ8byN5hhsjnffp2_iUi1xTAFu… - R.

In general when I call the command at the terminal it completes, when I call it from a pipeline it fails.  Kind regards, Tom Kirk _______________________________________________ Freesurfer mailing list Freesurfer(a)nmr.mgh.harvard.edu https://secure-web.cisco.com/1JdkmrC1kXzQ2NpLdVBqFN8spRaPaMdjYMqt7sisCWF9GD…

Resampling FLAIR images with anisotropic voxels
by Jin Liu 12 Nov '24

12 Nov '24

External Email - Use Caution Hello Freesurfer team, I tried to use SAMSEG-long to deal with my longitudinal data with paired MPRAGE and FLAIR images. But when I checked the original FLAIR images I have, I found that they have a voxel resolution of 1.333333 x 1.333333 x 2.000000. When I view it on Freeview, although the axial view is fine, only a rectangular portion of the sagittal and coronal brain is available, with the top and the bottom cut off. I guess it’s probably due to resampling issue that assumes isotropic voxels which we do not have. Is there any way to fix this problem? Best, Jin

Systematic difference in volume between baseline and longitudinal pipelines
by Sandhitsu Das 12 Nov '24

12 Nov '24

External Email - Use Caution I have seen some threads from a few years ago discussing differences in thickness, and we see this in volume as well (v6). See attached plot for left caudate volume. Ignore the colors of the scatter plot. I understand it is not meaningful to compare the base and long pipeline values, but I would like to understand the reasons behind it, particularly the directionality of the bias seen in the scatter.

aparcstats2table & asegstats2table version differences
by Heffernan, Zachary 12 Nov '24

12 Nov '24

External Email - Use Caution Hello FreeSurfer Mailing List, I see in the Release Notes<https://secure-web.cisco.com/1lK9mo_WphoqaD0OwDPzP8NYhd5OgBOqL-RwDbAarZRffE…> for v6.0 that there was a known issue affecting aseg.stats (description below). Was the patch fix fully integrated into subsequent releases? Am I correct in thinking unpatched v6.0 could yield incorrect results for voxels other than 1mm3 but that patched v6.0 or as-released v7.1.1 will yield correct results? The global morphometry statistics embedded in aseg.stats and other files have an error when the input volume has a voxel resolution different than 1mm^3. See MorphometryStats<https://secure-web.cisco.com/1rva3QX_QbO2BkaZ_SR7XkuA-u6d1TcBOVZG6kclkMMIwF…>. See BrainVolStatsFixed<https://secure-web.cisco.com/1nB-kiQZIQghPcWLIxNNlNwFlodDKdJPpJsxMYzldHaABd…> for the patch for version 6.

FYI: I just found a bug where recon-all will exit with error the second time it is run. This will be fixed in the final release. doug
