Re: [Freesurfer] T2 and control points

Dear Paul, maybe this is implicit, but to assure: you have also to include -autorecon3. Therefore the full command is: recon-all -s subject_id -autorecon2-cp -autorecon3 -T2pial Antonin Yes, I think so > On Feb 5, 2017, at 2:47 PM, miracoo...(a)gmail.com wrote: > > Hello, > I ran the entire recon pipeline with T2 option and then added control > points.

Percentage of cortex showing significant differences
by Bronwyn Overs 07 Feb '17

07 Feb '17

Dear mailing list, I have completed a matlab based lme analysis using cortical thickness, and now have a list of significant clusters for each coefficient. I now want to know what proportion of the cortex differs significantly for each coefficient. I can add up the total size of the significant clusters for each coefficient, but I don’t know what value to use in the denominator (the total size of the cortex). Would it be the total area of the fsaverage inflated surface that I used in my analysis? Kind regards, Bronwyn Overs Research Assistant Neuroscience Research Australia Margarete Ainsworth Building Barker Street Randwick Sydney NSW 2031 Australia M 0411 308 769 T +61 2 9399 1883 F +61 2 9399 1265 neura.edu.au <http://neura.edu.au/> <https://twitter.com/neuraustralia> <https://www.facebook.com/NeuroscienceResearchAustralia> <http://www.neura.edu.au/help-research/subscribe>

Regarding: mris_label2annot
by Dr Sampada Sinha 06 Feb '17

06 Feb '17

Dear freesurfer experts, I am trying to create medial temporal lobe and for that I ran the command mri_annotation2label to create ?h.entorhinal.label, ?h.temporalpole.label and ?h.parahippocampal.label from fsaverage and stored these labels in labels.?h directory. After this I ran mris_label2annot, taking cue from page https://surfer.nmr.mgh.harvard.edu/fswiki/mris_label2annot. My command line is the following (fsaverage has been linked to my subject directory: rmbp:AD Sampada$ mris_label2annot --s fsaverage --h lh --ctab /Applications/freesurfer/subjects/bert/label/aparc.annot.ctab --a myaparc --l ./labels_lh/lh.temporalpole.label --l ./labels_lh/lh.parahippocampal.label --l ./labels_lh/lh.entorhinal.label --nhits nhits.mgh However, it comes with following error *Writing annot to /Users/Sampada/Desktop/AD/fsaverage/label/lh.myaparc.annot* *could not write annot file /Users/Sampada/Desktop/AD/fsaverage/label/lh.myaparc.annot* *Permission denied* Will you please let me know how to fix this problem . I can see its a permission error but don't know how to overcome it. Thanks for your help Kind regards, Sampada -- Sampada Research medical scientist (B) Department of Geriatric Mental Health (DGMH) King George Medical University Lucknow-226003 , Uttar Pradesh India

Problem with using tksurfer to take snap shot with .tcl
by Hao wen 06 Feb '17

06 Feb '17

Hello: FS experts: I am now integrating to use tksurfer to take snapshot from command line automatically, and my command is like this: ``` cmd = "tksurfer %s %s inflated -tcl %s" % (subject, hemi, os.path.join(os.path.dirname(sys.argv[0]), "snap_tksurfer.tcl")) ``` so i use -tcl to define the behavior of tksurfer, but I go t a bug inside the tickle script, ##curv puts "shitaaaaa" puts stdout [pwd] puts stdout $env(SUBJECT_NAME) puts [trace vinfo lablpth] read_binary_curv puts "shittttttttt!!!, has bug here" I debug it and found that it can not really run this command: read_binary_curv, before, it can take some snapshots and save it to be rgb format, and i will also give you the output from the terminal: Successfully parsed tksurfer.tcl shitaaaaa /Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional sub-PREVDEMALS0010001BE_ses-M0 subject is sub-PREVDEMALS0010001BE_ses-M0 hemi is lh surface is inflated surfer: current subjects dir: /Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional checking for nofix files in 'inflated' Reading image info (/Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional/sub-PREVDEMALS0010001BE_ses-M0) Reading /Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional/sub-PREVDEMALS0010001BE_ses-M0/mri/orig.mgz surfer: Reading header info from /Users/junhao.wen/Hao/Dataset/test-data/recon-alled-result-1sub/analysis-series-default/subjects/analysis-series-default/subjects/sub-PREVDEMALS0010001BE/ses-M0/t1/freesurfer-cross-sectional/sub-PREVDEMALS0010001BE_ses-M0/mri/orig.mgz surfer: vertices=98465, faces=196926 surfer: single buffered window surfer: tkoInitWindow(sub-PREVDEMALS0010001BE_ses-M0) setting percentile thresholds (-1.00, 0.00, 0.00) surfer: using interface /Applications/freesurfer/tktools/tksurfer.tcl tksurfer: run tcl script: /Users/junhao.wen/Hao/Project/clinica_realted/CAPS_qa_clinica/snap_tksurfer.tcl Reading /Applications/freesurfer/tktools/tkm_common.tcl Reading /Applications/freesurfer/tktools/tkm_wrappers.tcl Reading /Applications/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /Applications/freesurfer/tktools/tkUtils.tcl Successfully parsed tksurfer.tcl reading white matter vertex locations...

freeview problem with w-file overlay
by Björn Herrmann 06 Feb '17

06 Feb '17

Dear list, I would like to use freeview to display my activations patterns. I source-localized MEG data in matlab using the freesurfer standard brain as a source space. I saved the source localization as a w-file, that is, as an overlay. I used to display the overlay in tksurfer, but I cannot adjust the colorbar thresholds using my keyboard in tksurfer (probably due to new linux and freesurfer versions). I read in an older post about that problem and it was suggested that freeview might be a better option. Unfortunately, I cannot load my w-files in freeview (similar problems as in the post below). Since I only work in matlab up to the point when I would like to save my data for plotting with freesurfer (e.g., freeview), I do not know how else (if not as a w-file) I could save my activations to display them as an overlay. I do not have volume data, I only have a vector of activation values corresponding to the vertices. Is there a different way to save my data in matlab so that I can display them as an overlay onto a surface in freeview? I would be thankful for any input. Best, Bjorn Older post below: Re: [Freesurfer] Loading .w surface overlay in Freeview can you use vol2surf to generate a .mgz/.mgh file instead?

Dear Freesurfer experts, I was curious whether there is any update regarding infant brain segmentation? Are the atlases going to be released anytime soon? Looking forward to your response. Best Alena
