There is not an error, per se. An ill-conditioned matrix means that your
design matrix has two or more columns that are too similar. Check your
continuous variables to see whether they are similar (eg, age and
education level). Finally, it is difficult to diagnose the problem
without more inf

When you say you can't get them to work, what exactly do you mean? Do you get
any console error messages? Do you get nothing? Are the processes still
lurking about
Hello,
I am configuring a Freesurfer installation for two different types of
computers (headless servers and workstations). For both sets of
computers we want any non-OpenGL commands that are run to first go
through python scripts which load balance (these are working fine);
however we have
I have spmregister (and spmregister-sess) working on 64 bit machines.
The fix is to set the FS_SPMREG_MATLAB to point to the 7.0.1 version of
matlab. In the NMR Center, you can just:
setenv FS_SPMREG_MATLAB /usr/pubsw/common/matlab/7.0.1/bin/matlab
You can do this without affecting the versi
Dan,
The GUI apps all use Tcl/Tk, and scuba2 and qdec also use Vtk and
KWWidgets. All the apps have wrapper scripts which call one or more of
the scripts tcl_setup, vtk_setup and kww_setup, which set paths to the
libraries, prior to calling the .bin. So for example, 'tkmedit' is a
wrapper script
Greetings Freesurfers,
I am using optseq2 for the first time to generate a stimulus order for my
trials and figure out the ideal ITI between trials. I have a few questions
about how this works.
1. I tried specifying the PSD max as 18 seconds and minimum of 2 seconds.
My ntp is 216 and my TR is
Hi,
I'm a new user and I'm having problem with some of the dicom data sets I

Hello all,
I was wondering if there is a quick way to make edits to multiple slices
of the aseg.mgz (or the brainmask.mgz) volume.
Specifically, I am working on my first subject, and it seems that on
almost every slice, pieces of the dura/skull/arachnoid/what-have-you get
segmented as cortex
Hi Chris,
what type of acquisition are you using? Dura can be really hard to deal
with, as it can look just like gm, depending on your MR parameters, and
it is can also be physically adjacent to gm. That said, it's only usually a
problem in localized areas. What resolution is your data? We hav
The acquisitions are SPGRs, taken on either a GE 3T or 1.5T (I'm not exactly
sure, I'm new to the job). Yea, in a lot of areas the dura is adjacent to the
grey matter. Those are certainly the problem areas - in most other areas the
segmentation is excellent. I'm not sure of the resolution.
---
you can use mri_info on your dicoms to find out the resolution. Hopefully
it's not too far from 1mm isotropic. If it's 1.5 or bigger in any
dimension that might explain the trouble.
