skull stripping and gcut error
by Jacquelynn Nicosia Copeland 05 Aug '11

05 Aug '11

Hi Freesurfers: I am trying to minimize the amount of skull stripping manual edits I need to make on Freesurfer outputs due to remaining dura. I've been trying both: adjusting the watershed parameters and using gcut. However, I noticed the output with and without gcut for the same participant were not different. So I went to the log file, and when I searched for gcut it says: " rm -f brainmask.gcuts.mgz mri_gcut -110 -mult brainmask.auto.mgz T1.mgz brainmask.auto.mgz brainmask.gcuts.mgz INFO: Care must be taken to thoroughly inspect your data when using mri_gcut. In particular, inspect the edges of gm and cerebellum for over-aggressive cutting. Add -segmentation brainmask.gcuts.mgz to the tkmedit command string to view the voxels which gcut has removed. reading mask... white mean: 107.529232 threshold set to: 107.529232*0.400000=43.011693 calculating weights... doing mincut... now doing maxflow, be patient... g-cut done! post-processing... post-processing done! masking... ** Gcutted brain is much smaller than the mask! ** Using the mask as the output instead! cp brainmask.auto.mgz brainmask.mgz " Thus, it does not appear to be using the brainmask with gcut edits. I added the "-segmentation brainmask.gcuts.mgz" to the tkmedit command and got an error basically saying that the file does not exist. This is the case for many of our participants. Why is this occurring? Isn't the purpose of gcut is to make the brainmask smaller (b/c it has less dura in it)? Also, any other suggestions for reducing remaining dura/skull? Thanks for any help you can provide, Jacquie Jacquelynn N.

dmri_train malloc error

Freesurfer users, I have ran into a malloc error running trac-all. Looks like the same error that Stijn posted to the list on 17 Jun 2011. I did not see a solution posted. It occurs in dmr_train using trac-all -prep –c dmrirc.txt. Also tried using trac-all –prior –c dmrirc.txt with the same results. Reset the tcsh limits for datasize, …. ********* Loading segmentation from /Applications/freesurfer5_1/trctrain/trc029/dlabel/mni/aparc+aseg.nii.gz Loading cortex mask from /Applications/freesurfer5_1/trctrain/trc029/dlabel/mni/cortex+2mm.nii.gz dmri_train(54615) malloc: *** mmap(size=159744) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug MRIalloc(218, 182, 182): could not allocate 158704 bytes for 26th slice Cannot allocate memory ********** My system Model Name: Mac Pro Model Identifier: MacPro3,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 2.8 GHz Number Of Processors: 2 Total Number Of Cores: 8 L2 Cache (per processor): 12 MB Memory: 18 GB System Version: Mac OS X 10.5.8 Thanks for any advice or suggestions!

So when viewing with tksurfer I am assuming that -map angle shows the polar data. It looks ok.

Can I use freesurfer to segment a phantom
by John Jan Drozd 04 Aug '11

04 Aug '11

Hi, I have MRI scans of a plastic polycarbonate ventricle that is an actual shape of a ventricle. It is in a brain mold of agar gel solution. I segmented the ventricle successfully using multiple seeds fuzzy connectedness in ITK. My segmentation was 97.2 % accurate. In ITK it had only single seed fuzzy connectedness but I adapted the code to work with multiple seeds. The reviewers of our paper want us to use FreeSurfer to segment the ventricles. Can I use freesurfer when the brain mold only has ventricles and grey matter (agar gel)? Or does Freesurfer require the brain to have the same number of brain parts as the Talairach atlas that it uses? My hunch us that it is the latter case. Thank you for your time.

Which hemisphere is in the sagital view of the wm
by Antonella Kis 04 Aug '11

04 Aug '11

Hi, When visualizing the wm.mgz in the coronal view we can see both hemispheres: lh and rh. How do I know which hemisphere I am visualising in a sagittal view? Do I have a transition from lh to the rh while passing through the slices? Thank you, Antonella

Hi - The txt files are missing for all the tracts as it turns out trac-all -prep exited with errors before getting to -prior. It appears there is a problem with my bvec file since the dmri/bvec is reading all 0's. As a result, i get this error "Error: bvecs and bvals don't have the same number of entries". I have attached my bvec.txt file and trac-all log - any ideas to where the problem may lie?

Bbregister & retinotopy

Dear Freesurfers, I've been troubleshooting my bizarre looking fieldsign data. I ran bbregister for my polar and eccentricity images, then re-ran the retinotopy analysis. The data still look the same. The fieldsign image is still a mass of blue and red speckles. Any tips on how I should proceed? Thanks. Michelle
