freeview showing results in a strange manner
by 姜时泽 22 Nov '18

22 Nov '18

External Email - Use Caution | | Dear freesurfer experts, I am using freesurfer to analyze my PET data according to the tutorial online. It works pretty well and I write the values of the results of each region to the template with Matlab (file attached here entitled "lh.subj1.mgz"). However, when I try to open it with freeview, the image looks quite strange ('Picture_1') but it works with tksurfer (Picture_2). Does any one know what is wrong with this? Did I plot the result in a wrong way? Thanks very much Shize -- Shize Jiang Fudan University, Department of neurosurgery, Huashan Hospital, Shanghai Medical College Shanghai,200032,P.R.China Mobile: (86)18317079839 E-Mail: sjiang13(a)fudan.edu.cn | | | |

External Email - Use Caution Dear Freesurfer users, I want to use the "Save Movie Frames..." in freeview to go through 305 frames of an overlay on a pial surface. When a select: Fly through Frame Start number 0 End number 305 Step size 1 I click "write" and it writes only one image and stops. Thanks for you help.

Average subject normal data base
by m s 22 Nov '18

22 Nov '18

External Email - Use Caution Hi, I am looking forward to create a normal database for daily use to compare with individual patient mr volumes. I was thinking about creating an average subject from a normal database of multiple subjects. After I have my average subject, would it be posssible and correct to compare this average recon individually to a new subjects recon, redoing all the averaging and comparing process only between this two? Thank you Mercedes

'lh_G_Ins_lg&S_cent_ins_volume' and 'lh_G_insular_short_volume'
by Christophe Destrieux 22 Nov '18

22 Nov '18

External Email - Use Caution Hi Rujing Sorry for the late answer. These 2 labels correspond to the insula The insula is divided by the central sulcus of the insula (S_cent_ins_) into long insular gyri (G_Ins_lg) and short insular gyri (G_insular_short). Since the cortex lining the central sulcus of the insula was quite small, it has been grouped together with the the long insular gyri ( 'lh_G_Ins_lg&S_cent_ins_volume’) If you are interested in the volume of the whole insula you need to add the volumes of these two anatomical classes. For a complete list of anatomical classes and explanations on their anatomical meaning see : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937159/ Best Christophe Destrieux, Unité iBrain UMRS INSERM U1253, Université de Tours https://ibrain.univ-tours.fr/ <https://ibrain.univ-tours.fr/> Service de Neurochirurgie et Laboratoire d'Anatomie - Faculté de Médecine - 10 Bd Tonnellé - 37032 Tours - France tel (33) 2 47 36 61 36 - fax (33) 2 47 36 62 07 > Le 21 nov. 2018 à 17:12, Bruce Fischl <fischl(a)nmr.mgh.harvard.edu> a écrit : > > you are getting very popular! > > > ---------- Forwarded message ---------- > Date: Wed, 21 Nov 2018 14:30:13 +0800 > From: charujing123 <charujing123(a)163.com> > Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> > To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> > Subject: [Freesurfer] 'lh_G_Ins_lg&S_cent_ins_volume' and > 'lh_G_insular_short_volume' > > > External Email - Use Caution > > Hi, what is difference between and 'lh_G_insular_short_volume'.

How to automate recon-all command for multiple subjects
by Vivek Sharma 22 Nov '18

22 Nov '18

External Email - Use Caution Hi, I'm using freesurfer to generate head surfaces using MRI file. I want to execute recon-all command for number of subjects, but unable to run it. The script I'm using is: for i in `cat *subs.txt*` do recon-all -s $i -all -qcache done subs.txt contains the name of folder that contains .nii file. The scripts ends with the following error: ERROR: no run data found in /cblhome/vivek/freesurfer/subjects/sub-CC110033_T1w/mri. Make sure to have a volume called 001.mgz in /cblhome/vivek/freesurfer/subjects/sub-CC110033_T1w/mri/orig. If you have a second run of data call it 002.mgz, etc. See also: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Conversion Linux cblhost 4.4.0-83-generic #106~14.04.1-Ubuntu SMP Mon Jun 26 18:10:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Please let me know how I can run recon-all for multiple subjects.

Corrupted T1 file (?) but segmentation look fine
by Anneliis Sartin-tarm 21 Nov '18

21 Nov '18

External Email - Use Caution Hello all, I have been running into a curious problem with a couple brains (8 out of 150 seem to have this problem) running through the recon-all pipeline. Upon loading brainmask.mgz, T1.mgz, and corresponding white matter and pial surfaces in Freeview, my colleague and I received an error that T1.mgz failed to load. Segmentation and parcellation seemed to run smoothly and accurately, however, the size of the T1.mgz file was 0. Assuming the file had been corrupted somehow (our server through which we run recon-all and store our data has tons of available memory), we reran the brains affected. Upon loading up the same re-run surfaces, T1.mgz loaded into the GUI as white, washed out voxels, displaying no brain at all. The size of this file is large, as well as all other surface and volume files. Curiously, the brainmask file seems normalized/stripped fine and surfaces displayed over the T1 look accurately segmented. I attached a screenshot displaying the T1.mgz file and surfaces that I'm referring to. I have a few concerns and questions. Because T1.mgz doesn't seem to be necessary for downstream manual editing and processing, can we proceed as normal, only displaying and using the brainmask file to make edits? Will our surface and volume metrics export properly without a usable T1 file? Lastly, any clues to how this might have occurred are welcomed. It seems like the mri_normalize step is the culprit, although the nu.mgz files corresponding to these brains seem normally sized.
