creating an entorhinal cortex volume from ?h.entorhinal_exvivo.label
by Mehul Sampat 26 Jun '13

26 Jun '13

Hi Folks, I am trying to create an entorhinal cortex volume from ?h.entorhinal_exvivo.label using mri_label2vol I cd to the subject dir ($SUBJECTS_DIR/bert) and the command I use is: *mri_label2vol --label label/lh.entorhinal_exvivo.label --temp mri/nu.mgz --identity --o mri/lh-new-erc.mgz * I took the sum of the voxels in this new mask i created (lh-new-erc.mgz) and it is 215; I looked at the volume provided in lh.entorhinal_exvivo.stats and it is 925; (from the log file I believe this is created using the command: mris_anatomical_stats -mgz -f ../stats/lh.entorhinal_exvivo.stats -b -l ./lh.entorhinal_exvivo.label bert lh white) I was expecting the numbers to match or at-least be close; I am guessing I am using mri_label2vol incorrectly ? Could someone help me with this issue ? Thanks Mehul

Inputs to recon-all -i
by ye tian 26 Jun '13

26 Jun '13

Dear freesurfers, I have a general question concerning *recon-all -i*. Suppose under the subject *Beth*, there are 256 files: Beth1.1.ima, Beth1.2.ima, Beth1.3.ima, ..., Beth1.128.ima Beth2.1.ima, Beth2.2.ima, Beth2.3.ima, ..., Beth2.128.ima I understand that I can use the following command to import the data *recon-all -s Beth -i /Path_to_Beth/Beth1.1.ima* * -i /Path_to_Beth/Beth2.1.ima* which gives 001.mgz and 002.mgz in the Beth/mri/orig/ Now what if I rename the sequence as follows, Beth2.1.ima -----> Beth1.129.ima Beth2.2.ima -----> Beth1.130.ima ...... Beth2.128.ima -----> Beth1.256.ima and import using *recon-all -s Beth -i /Path_to_Beth/Beth1.1.ima, *leading to 001.mgz alone. Would it make a difference? Thank you very much! Sincerely, Ye

The ill-conditioned error is probably not related to the contrast. It is usually related to the design matrix, which makes it difficult to track down because you will have a different one at each vertex with --pvr. doug On 6/13/13 1:14 PM, Gautam, Prapti wrote: Dear FreeSurfers I am trying to control for thickness in another surface using the pvr option in mri_glmfit.

But this option seems to be neither dods nor doss. Is there a correct way to do a DODS analyses looking for interactions using the pvr option?

Hi Ye you need to give recon-all a T1-weighted anatomical (e.g. mprage, SPGR/FLASH, etc...), not the fMRI data. cheers Bruce On Wed, 26 Jun 2013, ye tian wrote: > Dear Bruce, > > Recon-all exits with the following error > > ERROR: input(s) cannot have multiple frames! > $SUBJECTS_DIR/Barba50527_2/mri/orig/001.mgz has 439 frames > > If I open 001.mgz using freeview, I obtain the image in the attachment saved > as freeview 001.mgz.png. > > > > In order to make sure that my problem does not come from further upstream, I > am including the major steps that I took to get to this error. > > MAJOR STEPS > > STEP0: > My inherited data has names > BARBA50527.MR.MEDITATE_MEDITATION.#.#.year.month.day.#.#.#.#.#.IMA > where each # is a string of numbers. > > > STEP1: > The images can be grouped into five categories, according to the numbers in > the names that occupy the positions of the red #: 1.1-1.3, 2.1, > 3.1-3.160, 4.1-4.439, 5.1-5.439 > > [1] Note: Images from groups 4 & 5 are very different from the images of > groups 1, 2 and 3.
