Use mris_anatomical_stats. aparcstats2table is used for combining several outputs of mris_anatomical_stats. Alex Hanganu wrote: > Dear Chris, Doug, > > We created a ROI in qdec (EXMPL.label) and tried to measure it's > thickness. > > The cmd used: > aparcstats2table --hemi ?h --subjects 1 2 3 --

Does it look like that when you load the original analyze into tkmedit? andrewkra...@ucla.edu wrote: > Sure. Here's a screenshot of the orig.mgz. > > Quoting Bruce Fischl : > >> Can you send us an image? The 16 bit shouldn't be a problem >> Bruce >> >> >> >> On Feb 23, 2011, at 7:28 PM, andrewkra.

I actually didn't know you could load analyze into tkmedit, but now that I have, it does look like that too (just without the direction arrows). It doesn't look like that when I look at it in other viewing programs, though (it looks like you'd expect). -- Andrew Quoting Douglas N Greve : >

You have /stat/ rather than /stats/ in the address. Have you checked that? >>> Alex Hanganu 2/24/2011 12:22 PM >>> Dear Chris, Doug, We created a ROI in qdec (EXMPL.label) and tried to measure it's thickness. The cmd used: aparcstats2table --hemi ?h --subjects 1 2 3 --parc .../DIR/EXMPL.label

It looks the same to me in fslview. I'm guessing that there is a byte-swapping problem. Any chance the .img file was created under linux and the .hdr created under windows (or vice versa)? andrewkra...@ucla.edu wrote: > Sure. Since it's probably a bit big for email, I uploaded it to > http://dl

There's actually quite a large chance for that, as we convert the DICOMs to ANALYZE on iMacs; skull-strip mostly on PCs; register and do other processing on remote machines running OpenBSD, IRIX, and Linux (some of which are little-endian and some of which are big-endian); and then check ev

not an easy way. You'd have to find out what the byte swapping is in each file (or verify that the byteswapping is different). The other programs may check that the voxel values are "reasonable" and byteswap them if they are not. andrewkra...@ucla.edu wrote: > There's actually quite a large cha

Dear freesurfer experts, I have what I think is a fairly straighforward task, but the steps are not exactly clear to me. I wish to create a new label on the cortical surface and then map this label to each individual subject in order to extract roi data. I've successfully made my label on the co

I've played around with byteswaping, but alas it doesn't seem to be the issue. The original ANALYZE file is 16-bit little endian (or at least says it is), but when I swap just the .img to big endian and use the original header, or give the original .img a 16-bit big-endian header, the resul
