[Freesurfer] wmparc
Hi all, I am working with FS 4.5 and 5.0 and I have noticed that in wmparc.stats in 5.0 there are volumes (segmentations) that do not appear in the wmparc.stats file (and appear in 4.5 version), for instance the subcortical structures, ventricles, cerebellum. In wmparc V 4.5 I have 1189 rows with structures and in v 5.0 I just have 70. Why is this?

[Freesurfer] Volumes/Areas
Hi all freesurfers, What volume/area should I use to measure the motor cortex? Is there a way to measure the volume/area of medial or ventromedial prefrontal cortex?

[Freesurfer] medialorbitofrontal_area
Hi all, The total rh surface is always bigger than the lh surface (I've checked also the cerebral cortex volumes and the rh are also bigger than the lh volumes). I have the rh_medialorbitofrontal area bigger in 30 of my 32 subjects, but when I compare the lateralorbitofrontalareas, these appear to be good in the two hemispheres (is this normal this difference between the two hemispheres in the medialorbitofrontal and the similarities in lateralorbitofrontal areas?). The values are not wrong because of the bug in parac2table once I've checked it manually in aparc.stats files. Should I normalize the individual areas to the correspondent lh or rh hemisphere? What suggestions do you have? Thanks a lot for all the help, Jose. What's the total surface area of the rh? Is it bigger than the lh?

[Freesurfer] QDEC
Hi all, I am working with QDEC and I would like to know if it is possible to do subcortical structures (e.g. hippocampus, amygdala, putamen) analyses in qdec?? I only have cortical structures mapped in my analyses. Thanks for the help, Miguel.

[Freesurfer] Qdec white matter
Thanks Nick, my version is 4.0.3 on a linux 32bit. If you could send me the update I would be grateful. My point is to do a whitte matter comparison between two groups of subjects, with and without a pathology. I woul like to use white matter as I use cortical thickness (If it is possible), and not as a regressor. Thank tou for the help.

[Freesurfer] FS versions
Hi all, I am doing a study with FreeSurfer (80 subjetcs till now), and I have cases reconstructed with the versions 4.2 and 4.3. I want to continue the study, and install the 4.5 version. I saw that in this release the Destrieux Atlas was updated. Could i compare the cases from the versions 4.2, 4.3 and 4.5? Is it correct or I only should compare cases (volumes, thickness, ...) between the same version? Thanks for the help, Miguel.

[Freesurfer] qdec analyses
Hi all, I am a little bit confused about the qdec display. I have some simple questions about two groups A and B: 1- In the question, does the average thickness differ between A and B? How this average is calculated? By the difference between the A average and B average (avgA-avgB) ? The negative values (normally in blue) mean that the thickness (average of B) B is higher than A? 2- I want to analyze lh parahippocampal thickness. What is the difference between insert the values manually in the qdec.table.dat file (like the tutorial) or import ( in subjects - stats data import) the lh_parahippocampal_thickness from aparc? 3- In the question, does the thickness--lh_parahippocampal_thickness correlation differ between A and B? what for instance a positive value mean on display? I only expected results in the parahippocampal area... Thaks for the help, Miguel.
