selxavg3-sess /tmp dir out of space
by Jiahe Zhang 06 Jun '18

06 Jun '18

External Email - Use Caution Dear Freesurfer experts, While running selxavg3-sess on a large functional scan (7 Tesla, 768 time points), I got these errors gzip: stdout: No space left on device ERROR: /tmp/tmp8187256.nii, read in 1669519272 voxels, expected 3257077248 It sounds like there wasn't enough space on /tmp for an intermediate file to be written. Is there any way I can override the default so the intermediate file gets written to a location that does have enough storage space? Thanks, Jiahe -- Jiahe Zhang Ph.D. Candidate Department of Psychology Northeastern University 617-373-2649

External Email - Use Caution Good afternoon all, I am new to Freesurfer (using version 6.0) and trying to run recon-all on multiple subjects. Every subject exited with errors. Specifically, a number of surfaces are missing from the "surf" subject's folder (only 30 files instead of 80). Would you happen to know how to fix it? Taken from the recon-all status log: #@# Smooth2 lh Mon Jun 4 16:26:27 DST 2018 #@# Smooth2 rh Mon Jun 4 16:26:31 DST 2018 #@# Inflation2 lh Mon Jun 4 16:26:35 DST 2018 #@# Inflation2 rh Mon Jun 4 16:27:02 DST 2018 #@# Curv .H and .K lh Mon Jun 4 16:27:29 DST 2018 Linux Laptop 4.4.0-43-Microsoft #1-Microsoft Wed Dec 31 14:42:53 PST 2014 x86_64 x86_64 x86_64 GNU/Linux recon-all -s 1062_2 exited with ERRORS at Mon Jun 4 16:27:32 DST 2018 I have also attached a recon-all.log for your convenience.

seek for help about recon-all
by 姜时泽 05 Jun '18

05 Jun '18

External Email - Use Caution | | Dear freesurfer experts, This is Shize Jiang from China. I am trying to run recon-all with Linux and Mac. All these files are finished without errors. However, Most of my cases will finish with around 270Mb. I was taught the size of each subject should be around 400Mb. I am not sure if there are some problems with my file. Would you please help me to tackle this problem? Thank you very much. Attached is the recon-all log file for one case. Best regards 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 | | | |

matrix and contrast design for multi-centre study
by C.P.E. Rollins 05 Jun '18

05 Jun '18

External Email - Use Caution Dear Freesurfer developpers, I posted a while back asking how to control for scanner site in a multi-centre study. I think I now understand the formatting to do so for a DOSS model, but was wondering how this would look for a DODS model. There are 6 scanner sites and I also want to control for age and sex. However, there are no females in 3 of the sites. I tried to create the contrast for this but got the following error: ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08 -------------------------------- Possible problem with experimental design: Check for duplicate entries and/or lack of range of continuous variables within a class. If you seek help with this problem, make sure to send: 1. Your command line: mri_glmfit.bin --y rh.5.lgi.centre.mgh --fsgd FSGD_centre.txt dods --glmdir rh.5.lgi.centre.glmdir --surf fsaverage rh --C H-NH_centre.dods.txt 2. The FSGD file (if using one) 3. And the design matrix above Attempting to diagnose further SumSq: Min=1.000000 (col 4), Max=183.117447 (col 31) The scale is much different between columns 4 and 31, you may want to normalize by subtracting the mean and dividing by the standard deviation. My contrast was 1 -1 -1 -1 -1 -1 -1 -1 -1 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0.75 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 and FSGD attached (does not include full list of subjects). Thanks very much, Colleen

How to create my own ASEG and APARC atlases
by arsene ella 04 Jun '18

04 Jun '18

External Email - Use Caution Dear All, I have a set of 7 NIIFTI images (0.5 mm isotropic) : - 2 average brain images (one T1W_MPRAGE and one T2W_SPACE template ) - 3 Tissue Probability Maps (Gray Matter, White Matter, CSF) - 2 Atlases (One for Gray matter structures and another for Internal brain structures (or subcortical structures) ) segmented from mean images, labelled and annotated. My question is: *How to used these images to build Freesurfer-Like Atlases (.gca and .gcs) ?* For the .GCA, I don't really know what to set as Flagged Arguments... mri_ca_train -node_spacing 4 \ # ? -prior_spacing 2 \ # ? -parc_dir esegatlast \ # Is that the directory of my segmented subcortical structures? -xform talairach_one.m3d \ # All the files are aligned, so which transform shold I set here? -input flash30_avg.mgz \ # Should I set the T1W-MPRAGE average here? -input flash5_avg.mgz \ # Should I set the T2W-SPACE average here? $SUBJECTS multi_one.gca What about the .GCS? Thanks in advance, Arsene

Re: [Freesurfer] Lookup table to surface overlay
by Funk, Quentin 04 Jun '18

04 Jun '18

External Email - Use Caution Freesurfer Experts, thanks for the response! There was no command for projabs, but looking through the help I think projdist was about what I needed? I was also curious though if there were a way to get it into an annotation--like the one available for the Yeo parcellations on the freesurfer webpage. Is there any way to convert a lookup nifti to an annotation, or one of these surface overlays into one? I can't seem to figure it out from the documentation, but it's almost surely user error...

Visualizing Supratentorial volume
by James Gullickson 04 Jun '18

04 Jun '18

External Email - Use Caution All, Is there any way to graphically visualize the segmentations for SupraTentorialVol and SupraTentorialVolNotVent, for example in freeview or tkmedit? Based on the descriptions I have read for the supratentorial values, I want to use them for an analysis. However, I would like to visualize them in my data set for QA purposes to ensure they are capturing what I think they are capturing. Thanks, James

Unpacking ASL scans
by Nasiriavanaki, Zahra 04 Jun '18

04 Jun '18

Dear Freesurfer developers Hi We collect a new ASL sequence at Bay 4 with Prisma. The scanner outputs a 3D mosaic. The problem is that unpacksdcmdir doesn't seem to work correctly on it so it results to an error! Is there any command other than unpacksdcmdir for unpacking the ASL scans? Thank you Mona Nasiriavanaki
