query regarding creating an atlas from nifti volumes.
by Mageshwar Selvakumar 05 Apr '18

05 Apr '18

Dear All, I am a newbie to freesurfer and I would like to use our in-house built probabilistic atlas(each region as a binary mask and available as nifti files). I would like to create an atlas out of it and use it for our analysis. On searching the previous mailing list I came across a discussion where the volume information was converted into surface information and can be converted to labels and annotations but I couldn't find much documentation on creating an atlas directly from the volume or surface information. It would be nice if someone can point me out if this is possible and some relevant information to continue on it. Thank you, Kind regards Mageshwar Selvakumar, M.Sc Department of Pharmakologische Bildgebung und Bildanalyse Friedrich Alexander Universität Erlangen Nürnberg Office: Fahrstr. 17, 91054 Erlangen Phone: + 49-9131-8522898

Re: [Freesurfer] error rerunning recon-all (exited with ERRORS)
by Anna Daniels 05 Apr '18

Hi Douglas, thank you for the quick reply! That helped for the first hard failure. Do you have any idea what could have caused the second error message? This only happened for some subjects when rerunning recon-all with -autorecon2 -autorecon3, but always resulted in this error log: Iterating 2 times --------------------------------- 3d normalization pass 1 of 2 white matter peak found at 110 Cannot allocate memory Linux node098 2.6.32-696.20.1.el6.x86_64 #1 SMP Thu Jan 25 08:47:49 CST 2018 x86_64 x86_64 x86_64 GNU/Linux recon-all -s 44538_T1_fs_edit exited with ERRORS at Do 29.

Abstract submission deadline extended - 1st International Workshop on Predictive Processing
by Sanjeev Nara 05 Apr '18

05 Apr '18

Hello Researchers, We have received request from lot of researchers to extend the deadline for abstract submission, We are happy to announce that the deadline for abstract submission for 1st International Workshop on Predictive Processing (WoPP) has been extended upto 16th April 2018. Hope to see you in San Sebastian. on behalf of Organisers Sanjeev Nara Predoctoral Researcher BCBL www.bcbl.eu https://sites.google.com/view/sanjeev-nara/ Abstract submission deadline extended - 1st International Workshop on Predictive Processing We would like to inform you that the abstract submission deadline to PREDICTIVE PROCESSING has been extended. The new deadline is April 16th. The conference dates are June 20-22, 2018 Dear Researcher, We are happy to announce the new discussion arena fully centred on predictive processing. The Workshop on Predictive Processing (WoPP) will take place in San Sebastian (Spain) on June 20-22, 2018. The goal of the workshop is to address the role of predictive processing in cognition. Some of the crucial issues in this timely research topic are the extent to which prediction is a fundamental mechanism of brain function, the role of prediction in learning, and, how predictive processing is expressed across distinct cognitive domains. This workshop will gather experts from different fields in cognitive neuroscience including sensory processing, attention and memory, to work alongside the community of language processing, with the aim of furthering our understanding of the role of predictive processing in cognition. We invite submissions from researchers genuinely interested in discussing their data within the framework of the prediction view on neurocognition and brain functioning. The conference will include keynote speakers, regular talks, symposiums and poster sessions. Keynote speakers will be the main sources of discussion: Sophie Scott , University College London Moshe Bar , Bar-Ilan University Pascal Fries, Ernst Strüngmann Institute (ESI) Each keynote will be followed by a symposium on a related topic. Each symposium will be co-organized by two experts in the field, and will last 2 hours. Symposium organizers are Gina Kuperberg, Matt Davis, Craig Richter, Julien Vezoli, Lucia Amoruso and Ruth De Diego Balaguer. For further information please visit: http://www.bcbl.eu/events/prediction-2018/en/ We look forward to seeing you at the conference. Yours sincerely, The Organizing Committee Manuel Carreiras, Clara Martin, Nicola Molinaro & David Soto IMPORTANT DATES TO REMEMBER: Abstract submission and Registration OPEN Abstract deadline: April, 6th, 2018. Extended until April 16th, 2018. Notification of abstract acceptance : April 24th, 2018. Early registration deadline: May 11th, 2018. Online registration deadline: May 30th, 2018. Conference dates: June 20-22, 2018. BQ_BEGIN BQ_END

MRIxfmCRS2XYZtkreg function
by Ricardo Valle 04 Apr '18

04 Apr '18

Dear Freesurfer community, I have stumbled upon a function called MRIxfmCRS2XYZtkreg in the Freesurfer source code on Github. It is used in several places but does not seem to be defined anywhere in the repository. Is it part of some external library? Would it be possible to take a look at its source? Thank you. All the best, Ruy

Dear FreeSurfer Experts, Am wondering if there is a way to extract morphometry (cortical thickness, area, etc) values from a specific co-ordinate (talaraich, MNI, etc) of interest. Any help with this will be appreciated. Kind regards Emmanuel

Still stuck - I downloaded the bin for mris_left_right_register from https://gate.nmr.mgh.harvard.edu/safelinks/greve/mris_left_right_register and ran it from the fsaverage surf directory: $PROJECTDIR/mris_left_right_register lh.sphere rh.sphere lh.sphere.left_right rh.sphere.left_right (Yes, it really should be in $FREESURFER_HOME, but I don't think that's the problem.) it fails with: $Id: mris_left_right_register.c,v 1.2 2011/12/16 20:49:37 greve Exp $ $Id: mrisurf.c,v 1.781 2016/06/13 21:20:50 fischl Exp $ reading lh surface from lh.sphere... reading rh surface from rh.sphere...

FSGD file error
by Dijkshoorn, A.B.C. (Aicha) 04 Apr '18

04 Apr '18

Dear free surfer developers, When I try to run the mri_glmfit free surfer does not seem to recognise my FSGD file. I believe it has something to do with the underlying languages, since it appears to occur both when I create a plain txt file or when I adjust the tutorials gender_age.fsgd and adjust the values of the covariates. I have tried tons of things to fix the problem, but i can't seem to figure it out... Do you by any chance have an idea on how I can fix this? error (in bash): ERROR: matrix is ill-conditioned or badly scaled, condno = 15250.9 command line: mri_glmfit --y lh.CB10.thickness.20.mgh --fsgd doesnotworkretestCB10.fsgd doss --C con-hem.mtx --surf fsaverage lh --cortex --glmdir lh.CB10.20.thickness.glmdir Thank you in advance for your time and effort! Kind regards, A. Dijkshoorn
