Re: [Freesurfer] sclimbic sometimes does not detect left basal forebrain
by Miriam Taza 13 Sep '22

External Email - Use Caution Hello, Im wondering if there is an update regarding etiv differences between recon all and using sclimbic. I want to divide the volumes extracted from using sclimbic on t1s by etiv. Im not sure given the discrepancy if I should use etiv extracted from recon all command or from sclimbic. Thanks, Miriam ________________________________ From: Miriam Taza <miriam.taza(a)mail.mcgill.ca> Sent: Thursday, August 11, 2022 6:01 PM To: Greve, Douglas N.,Ph.D. <dgreve(a)mgh.harvard.edu> Subject: Re: [Freesurfer] sclimbic sometimes does not detect left basal forebrain Hello, I just wanted to follow up about etiv, if you had the chance to look into if your recon all vs sclimbic also does simithing similar on the subjs i sent? I am also attaching another graph that depicts the difference between etivs extracted from sclimbic and from recon all.

I also included the stats file when I run sclimbic for reference. Please let me know if this mode of transfer works. Thank you, Miriam P.S. I also sent a previous email regarding etiv values "etiv value differs if using recon all vs freesurfer dev". Are you able to also see if your sclimbic etiv values differ much from recon all? For example, sub1221084 etiv greatly differs between sclimbic, old recon all, and new recon all. ________________________________ From: Douglas N.

Re: [Freesurfer] Follow Up License Freesurfer 5.3 Ubuntu

External Email - Use Caution The glibc version has changed in newer versions of Ubuntu.  That and/or changes to encryption related functions is likely preventing the license decoding from working.   Binary backwards compatibility cannot assure old binaries will indefinitely run on newer releases of the operating system., e.g., CentOS6 binaries may not run on CentOS8.  Freesurfer 5.3 was released in 2013 at the time of Ubuntu 12 so I would not assume it will run on Ubuntu 18 and/or newer versions.  I don['t think LD_LIBRARY_PATH will help with statically linked binaries - and sertting it to point to a version could break dynamically linked binaries with RPATH strings.  In general it is a bad idea to be running with different versions of glibc on the same system. There is an Ubuntu 12 VM running Freesurfer 5.3 available from https://secure-web.cisco.com/1X4Gyy7SfMYdVSIKIWMlCS7GCLmcJfLLRdLZ…;  That VM still runs in VirtualBox on todays operating systems.  - R.

Grey matter was not included in pial surface
by DINGLAN TANG 13 Sep '22

13 Sep '22

External Email - Use Caution Hi, I ran recon-all for my participants (T1 and T2, DICOM*.nii). but for some of my participants (3 out of 15), the grey matter was not correctly traced. Its overlapping with the white matter boundary. See image below. I have searched the list and no similar errors have been reported. Does anyone have any thoughts or suggestions on how to trouble-shoot this? [cid:image001.jpg@01D8C75F.1EE738C0] Best wishes dinglan

Extract Fetal Brain MRI
by Xuchu Liu 13 Sep '22

13 Sep '22

External Email - Use Caution Hi Dear, We are a research team at Rush University Medical Center. We are working on the Fetal MRI data. In this step,*we need to extract the "Fetal Brain MRI" from our images, which have "mother and other tissues"* as well. One of our options is using "FreeSurfer" Software. But before that, we want to make sure that "Freesurfer" is able to extract the "Fetal brain", from other tissues in the MRI. Could you guide us that this software can help us for this problem? Thanks, Xuchu, Rush University Research Team

MNI coordinates of minimal thickness in ROI

External Email - Use Caution Dear Experts, I am looking for a way to extract information on the location (xyz coordinates in MNI space) of a vertex with the lowest thickness value within an ROI (label) for a group of subjects. I have previously ran recon-all and qcache on the data. Any insights will be welcome!

volume differences between longitudinal and crosssectional preprocessing
by Bernardoni, Fabio 13 Sep '22

13 Sep '22

External Email - Use Caution dear freesurfer experts comparing the results of longitudinal vs. crosssectional preprocessing for single time point participants I have noticed that there are some quite substantial differences (>5% for some sub cortical regions). I wonder whether this is normal, or whether I should suspect that I am using some wrong setting. the differences are there both when using freesurfer 5.3 and freesurfer 7.1. I have always used the flag: -nuintensitycor-3T (our scanner is a 3 Tesla one) I would say that I more often have smaller volumes in the longi preprocessing (80% of the cases), but I haven't checked this systematically.
