Hemant, We dont have any cards here that are compute capability 1.0. Our test cards are all 1.3 or higher. We do compile with -arch sm_11 (compute capability 1.1). I've recompiled mri_em_register_cuda and mri_ca_register_cuda with -arch sm_10 and put them here: https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/linux-centos4_x… i dont know if they will work for you though. n.

mri_surfcluster .w input from MEG/EEG data
by raij＠nmr.mgh.harvard.edu 31 Oct '11

31 Oct '11

Hi Doug and Matti, I am using mri_surfcluster to threshold and extract ROIs from MEG/EEG source analysis data. The same code used to work fine in Jan 2009, but now I am running into unexpected errors. I wonder if something happened along the way of FreeSurfer and/or MNE stream upgrades and now mne_analyze .w files and mri_surfcluster no longer talk to each other. I first run the usual MEG/EEG analysis using the MNE stream and then save the resulting dSPM map on the surface of the subject as a .w file (using the mne_analyze GUI). For sanity check, I download the overlay in tksurfer and observe that it looks fine (which makes me think that the problem originates at the mri_surfcluster side rather than at mne_analyze; however, see below for evidence suggesting the opposite). on machine adapt nmr-std-env (=FreeSurfer 5.1) mne_setup cd /cluster/scratch/monday/raij/MEEG setenv SUBJECTS_DIR /cluster/scratch/monday/raij/MRIs/ setenv SUBJECT Wyss_000 mri_surfcluster \ --subject Wyss_000 \ --hemi lh \ --in AVL_GA_List1-00150.0-lh.w \ --frame 0 \ --thmin 2 \ --thsign abs \ --minarea 100 \ --olab test01 \ thsign = abs, id = 0 version $Id: mri_surfcluster.c,v 1.51.2.1 2011/03/28 15:32:36 greve Exp $ hemi = lh srcid = AVL_GA_List1-00150.0-lh.w srcsubjid = Wyss_000 srcsurf = white srcframe = 0 thsign = abs thmin = 2 thmax = -1 fdr = -1 minarea = 100 xfmfile = talairach.xfm nth = -1 subjectsdir = /cluster/scratch/monday/raij/MRIs/ FixMNI = 1 ------------- XFM matrix (RAS2RAS) --------------- /cluster/scratch/monday/raij/MRIs//Wyss_000/mri/transforms/talairach.xfm 0.973 -0.031 -0.031 0.033; 0.001 0.989 0.327 -34.515; 0.008 -0.285 1.073 -30.192; 0.000 0.000 0.000 1.000; ---------------------------------------------------- Reading source surface /cluster/scratch/monday/raij/MRIs//Wyss_000/surf/lh.white Done reading source surface Computing metric properties Loading source values mri_read(): couldn't determine type of file /autofs/cluster/scratch/monday/raij/MEEG/AVL_GA_List1-00150.0-lh.w ERROR: could not read AVL_GA_List1-00150.0-lh.w as type If I try to convert .w to .mgz I get the error mri_convert AVL_GA_List1-00150.0-lh.w AVL_GA_List1-00150.0-lh.mgz file not found or unknown file type for file AVL_GA_List1-00150.0-lh.w (which makes me think that perhaps the .w file from mne_analyze is incompatible with much of FreeSurfer 5.1 code) Any suggestions?

Fornix in corpus callosum segmentation
by Miguel Burgaleta 31 Oct '11

31 Oct '11

Hi Freesurfers, I'm using FS 4.5.0 to calculate the volume of the corpus callosum, but in about 70% of my subjects (n = 100) I get mild to severe inclusions of the fornix in the central and/or mid-posterior sections of the CC. Is there any workaround for this particular issue, before start considering manual editing? Thanks, Miguel

Re: [Freesurfer] white matter volume in a ROI
by Douglas N Greve 31 Oct '11

31 Oct '11

Your ROI must be listed in the color table, so you'll need to create a custom color table. For this you will need the ID eventually assigned to your ROI. To find this out, load the wmparc your created in tkmedit as both a segmentation and as the aux volume. When you click on your ROI, the tkmedit control window should show the name of your ROI. The "aux" field will show a value. This is the value you need. doug dolphinede(a)aol.com wrote: > Hi Doug, > > thanks a lot for your reply. > > I have run the following command to get wm volume stats of my ROI: > > > mri_segstats --seg > /Users/dolphinede/Desktop/Probanden/ARS23/mri/wmparc.mgz --sum > /Users/dolphinede/Desktop/Probanden/ARS23/stats/wmparc.stats --pv > /Users/dolphinede/Desktop/Probanden/ARS23/mri/norm.mgz --excludeid 0 > --brain-vol-from-seg --brainmask > /Users/dolphinede/Desktop/Probanden/ARS23/mri/brainmask.mgz --in > /Users/dolphinede/Desktop/Probanden/ARS23/mri/norm.mgz > --in-intensity-name norm --in-intensity-units MR --etiv --subject > ARS23 --surf-wm-vol --ctab > /Applications/freesurfer//FreeSurferColorLUT.txt > > But I think it is not right cause my ROI, my annotation is not listed > there in the wmparc.stats.

mris_pmake error
by Steph Bickel 31 Oct '11

31 Oct '11

Hi, when trying to use mris_pmake I get error messages: when I run:mris_pmake I get: sh: cannot create lock: Permission denied mris_pmake I'm sorry, but an error condition has occurred. While I was checking on the options file, I couldn't access the options file. Does it exist? Exiting to system with code 40 When I run: sudo ./bin/mris_pmake I get: mris_pmake I'm sorry, but an error condition has occurred. While I was processing environment, it seems that the SUBJECTS_DIR env variable is not set. Exiting to system with code 10 I did specify SUBJECTS_DIR in SetUpFreesurfer.sh that I source in the bashrc file and the variable is set for the other freesurfer functions. I am using freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 on ubuntu 11.04. Any help is much appreciated. thanks, Stephan

FW: Question on mris_pmake

Regarding my first question in my previous post below, the same error occurs even when I run my script (containing many repetition of mris_pmake command) on only one terminal window. From: Jungwon Ryu [mailto:rjungwon@snu.ac.kr] Sent: Tuesday, October 25, 2011 8:11 PM To: 'freesurfer(a)nmr.mgh.harvard.edu' Subject: Question on mris_pmake Hi, I'm trying to get distances on a cortical surface between sets of voxels in visual areas and I have two questions; 1) I have the following error message so often; === System error: Address already in use Fatal error encountered. SSocket `Unnamed SSocket_UDP_receive' (id: 0) Current function: c_SSocket_UDP_receive::c_SSocket_UDP_receive Problem binding to socket 1701 Error returned from system: Address already in use Throwing exception to (this) with code 1 terminate called after throwing an instance of 'c_SSocket*' runSh_Ori_1_02_01.sh: line 5789: 93334 Abort trap mris_pmake --subject JR20110819 --hemi rh --surface0 white --curv0 sulc --curv1 sulc --mpmOverlay euclidean --mpmProg pathFind --mpmArgs startVertex:907,endVertex:731 >> result_Ori_1_02_01.txt === I have around 10,000 voxel pairs to run mris_pmake( ) command. Since I have to call mris_pmake( ) so many times (one pair by one pair), I splitted the whole list of voxel pairs into four script files, containing many mris_pmake commands with 2,500 voxel pairs as arguments, then I ran scripts with four terminal windows saparately to parallelize the processing. All script files are located in the same diretory. Then I had the message as above. What might be the problem? (It seems as if multiple terminal instances share the socket port number) 2) How can I get interhemispheric distances between visual areas across hemispheres?

Sag3D_T1 or Axial_T1
by Antonella Kis 31 Oct '11

31 Oct '11

Dear Freesurfers, I have a set of MRI data collected in an Axial_T1 and some in Sag3D_T1. I wonder if after dcm to nii conversion when I get a 3D or 4D volume (if further use for FSL) it really matter how my data was acquired (Axial or Sag) since the NIFTI file is in fact a volume. Should I do a conversion for all the files in Axial or Sag? I am planning to use this data in Qdec and also in FSL to do some DTI studies, so I will need to register this data into MNI space. Also, how I can cut from the nii file's slices in order to bring two files to the same dimensions (x, Y, Z)? Many thanks, Antonella

Cluster-wise simulation in small samples

Dear Freesurfers, Could you please tell me about your experience with cluster-wise correction for multiple comparisons in relatively small samples. For instance, is it wise to use CWS for regression with one continuos variable in n=30 sample? --- Regards, Alex

Use mri_segstats. You can look in the recon-all.log file in subject/scripts.
