Re: [Freesurfer] Correction of registration in preproc-sess stream
Dear Doug, I have tested the various options of register-sess. The result was a succesful registration of the functional to the anatomical image. This registration with register-sess is performed after preproc-sess failed to achieve a proper registration. The register.dof6.dat file is updated by register-sess. I would like to ask a last thing just in order to make it definite. Can I now use those data for example with selxavg3-sess in order to compute the activated areas for this subject?

Re: [Freesurfer] DTI question
Not sure if this is the simplest way but mri_convert --split, followed by mri_concat, should do it. You'll also have to remove the respective gradient directions from the gradient file.

Re: [Freesurfer] Correction of registration in preproc-sess stream
You should run preproc-sess again to make sure that all the files that need to be updated after the registration are properly updated. This should not change the registration -- it should just look at the time stamps of the files and update any that need updating. However, if the files earlier in the stream were changed at some point, then it might try to regenerate the registration, so just in case make a backup of your registration files before running preproc-sess. doug On 06/27/2012 08:08 AM, Jörg Pfannmöller wrote: Dear Doug, I have tested the various options of register-sess.

Re: [Freesurfer] Correction of registration in preproc-sess stream
P.S.:I executed the following sequence to achieve the first level analysis with a correct registration. preproc-sess -s session_id -fsd bold -sliceorder siemens -surface fsaverage lhrh -mni305 -fwhm 0 -per-run register-sess -s session_id -fsd bold -per-run -init-header preproc-sess -s session_id -fsd bold -sliceorder siemens -surface fsaverage lhrh -mni305 -fwhm 0 -per-run -noreg -regfile session_id/bold/001/register.dof6.dat -force selxavg3-sess -s session_id -analysis stim.sm0.lh -no-preproc As far as I can see this is the right procedure. Do you agree or is there another or simpler way to correct the registration and proceed with a first level analysis? ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

[Freesurfer] Hippocampal segmentation
Dear FreesurfersI'm starting to deal with the FS v5.1 hippocampal subfields segmentation, and I have a couple doubts...If I have my subjects segmented from an older FS version, Would be any problem when running the -hippo-subfields?I'm guessing not, but I wanna be sure. Because, as I've looked the -hippo-subfields recon seems to not modify the whole brain segmentation, am I right?second, when I apply the kvlQuantifyHippocampalSubfieldSegmentations.sh I do obtain two txt files containing such segmentation of the 8 hippocampal subfields, but at the beggining it appear a field for the left and right hippocampus, but I don't know exactly what does this column represents, because if I sum the other colums the subfield sums are so much bigger than the hippocampus field; i.e.volume_in_number_of_voxels Left-Hippocampus left_presubiculum left_CA1 left_CA2-3 left_fimbria left_subiculum left_CA4-DG left_hippocampal_fissurec_12_hipo 3789.97 3215.08 2654.65 7705.2 336.857 4841.63 4158.49 356.626and last. Do I need to somehow do some partial volume corrections to this output volumes? Because the txt file sais nonPartialVolumeStats, and I'd saw on the page that the output is 0.5*0.5*0.5mm^3.

[Freesurfer] DODS, DOSS, and interactions
Freesurfers- Question, when looking for interactions to justify using DOSS say i am looking at cortical thickness and i have two discrete variables (G1 and G2) and 4 continious variables (V1, V2, V3, V4). My thinking is that i should look to see if there are interactions with the groups and each individual variable. However what if it is likely that an interaction of G1, G2, and V1 can be explained by V2? Michael -- Michael D.

Re: [Freesurfer] DODS, DOSS, and interactions
If the covariates are collinear, then you can't properly estimate the model. They are collinear if they explain the variance of each other. I would first test for the relationship of your covariates before putting them into the model as you don't want the covariates to be collinear. Best Regards, Donald McLaren = D.G.

[Freesurfer] selxavg3-sess error
