Re: [Freesurfer] lh.pial lh.pialT1n same file?

External Email - Use Caution Dear Yujing: I wasn’t aware that there was an answer to my email that’s the reason it took me a while to write back. But I answer here. Yes I mean lh.pial.T1. I don’t have any other lh.pial. The recon-all command is properly correct like recon-all -all -i -s -openmp 8. Yes the freesurfer version is 7.1.1. Best, Rene Andrade. Hi Rene, Do you mean lh.pial.T1? Do you have any other lh.pial* files in the directory? What is your recon-all command line? And can you also provide the Freesurfer version you are running? Best, Yujing -----Original Message----- From: freesurfer-boun...(a)nmr.mgh.harvard.edu <freesurfer-boun...(a)nmr.mgh.harvard.edu> On Behalf Of Renew Andrade Sent: Tuesday, December 13, 2022 7:24 AM To: freesurfer(a)nmr.mgh.harvard.edu Subject: [Freesurfer] lh.pial lh.pialT1n same file? External Email - Use Caution Dear experts: I am wondering if lh.pial and lh.pialT1 are the same files. I don’t have lh.pial is that an error from recon-all? Should I rerun recon-all. Or just autorecon-pial? Would that change anything?

External Email - Use Caution Dear Freesurfer group, Could you tell me which is the flag I need to use to get all the brain parcellation when I run recon-all? It seems I am getting the tables with few volumes and I guess there is something wrong. Best wishes and Merry Christmas, Rosie

questions about mri_glmfit
by James Brown 21 Dec '22

21 Dec '22

External Email - Use Caution Dear Freesurfer experts, I have 2 questions about the command mri_glmfit and I appreciate your help. 1- Are there any settings or flags that can be used in mri_glmfit to restrict statistical comparison of surface based analysis to specific ROIs rather than whole brain analysis. I would like to show the difference on the brain surface in lobes rather than in sub lobar labels. 2- I understand that the flag "--table" in command mri_glmfit allows for feeding spreadsheets instead of images. Can we restrict the number of columns in this spreadsheet to 8 columns for lobs (frontal, temporal, occipital and parietal) left and right? Also, is there any way to generate a statistical map from the spreadsheet statistics? Thank you and happy holidays :) James

mri_sclimbic_seg patch issue?
by daedalus39＠aol.com 20 Dec '22

20 Dec '22

External Email - Use Caution Dear FreeSurfer Developers, We are interested in implementing " mri_sclimbic_seg " from FreeSurfer 7.3.2 and are having trouble getting it to finish processing. When I tried to runmri_sclimbic_seg. I keep getting a python error and the process never finishes.I searched through the forum and it said that this was a known error and thatthere was a patch. When I installed the patch I got the exact same error. The error message is: “ValueError: operands could not bebroadcast together with shapes (4,) (3,)” The link to the forum post is: https://secure-web.cisco.com/1BI_B41UWHwWJM3wQhzsqKLiN64Mdzk_AasgGunt7xAFi2… We tried running it on the test subject “bert” just to makesure the issue is not with our test scan and I got the same error. We are getting the erroreven after installing the patch. Here are the details of the commandline I used to run it and the error message: Command line: mri_sclimbic_seg --s bert --o/usr/local/freesurfer/7.3.2-1/subjects/bert/mri/mri_sclimbic_seg.mgz--write_volumes --write_qa_stat Error: Traceback (most recent call last): File "/usr/local/freesurfer/7.3.2-1/python/scripts/mri_sclimbic_seg",line 1049, in <module> main() File"/usr/local/freesurfer/7.3.2-1/python/scripts/mri_sclimbic_seg", line232, in main segmenter.process_files(**params) File "/usr/local/freesurfer/7.3.2-1/python/scripts/mri_sclimbic_seg",line 578, in process_files post, seg, vox_counts, volumes,mean_probs = self.segment(image) File"/usr/local/freesurfer/7.3.2-1/python/scripts/mri_sclimbic_seg", line498, in segment conformed = self.preprocess(image) File"/usr/local/freesurfer/7.3.2-1/python/scripts/mri_sclimbic_seg", line490, in preprocess processed =image.conform(shape=(*self.inshape, self.nchannels), voxsize=1.0,orientation='RAS', dtype='float32', copy=False) File "/usr/local/freesurfer/7.3.2-1/python/lib/python3.8/site-packages/surfa/image/framed.py",line 574, in conform conformed = conformed.reshape(shape,copy=False) File"/usr/local/freesurfer/7.3.2-1/python/lib/python3.8/site-packages/surfa/image/framed.py",line 515, in reshape delta = (np.array(shape) -np.array(self.baseshape)) / 2 ValueError: operands could not be broadcast together withshapes (4,) (3,) We are beginning to study professional and amateur fighters, and we suspect that shearing/disruptions to the septum pellucidum may have downstream consequences to the connectivity/DTI measures in the septal nuclei, mammilary bodies, etc. Thanks in advance for any help or comments you can provide.
