Hello,
I want to do an analysis with 1 Group (Control and HIV) with two covariates
(Age and ICV). Qdec only lets me choose one covariate. So instead I
choose two nuisance variables. No matter how many different permutations I
run on this, I can not get it to duplicate my SAS results, and the Qd
Hi all,
I'm having trouble getting anything through on 5.1 using scripts, although
I can run recon-all at the commandline. I'm running freesurfer on a remote
cluster, not locally. Specifics of the cluster itself aside, with 5, I
could run:
*vbbatch -c *
*"PATH=$PATH:/usr/local/freesurfer_64bit_5;
Dear Freesurfers,
I'm really glad to see the (relatively) new functional connectivity
commands. It seems to be working really well.
Has anyone tried to do task-related functional connectivity? I would like
to compare functional connectivity with the hippocampus during two
different conditions of

In matlab
Xsss = sqrt(sum(X.^2));
Xn = X ./ repmat(Xsss,[ntptot 1]);
Then look at the condition of Xn

Thank you Prof. Greve. Hope all is well on your side.

It is okay to study a single cohort with covariates.

Dear Freesurfer Experts,
For one of our studies, I have used QDEC to analyze the relationship
between cortical thickness and a series of variables.
I wanted to double check to see if it is okie to have a qdec table which
only includes the diseased population and the covariates (such as FSIQ).

Aiko,
Per question (1), there will always be slight differences due to the
nature of our algorithms, but the thing to do to convince yourself that
the differences are not significant is to conduct a group analysis
(following the procedures we describe in our tutorials) comparing say
4threads to 8t
Dear all,
I would like to apply a bandpass filter both to my fMRI data as well as to
regressors in my GLM. I was wondering whether anyone has suggestions for
particular filter types and filter orders?
I find this seldomly reported in fMRI papers.
I was thinking in using Matlab's filtfilt.
Any sugge
Hi Akio
we are going to work our way through the time-intensive binaries and
parallelize them, but it will take us time to get to them.

Hi Nick,
I confirmed that the program run in multi-thread mode by adding the
"-openmp" flag. Thank you so much for your help.
May I ask a few more questions?
(1) Again, I find minor difference between the two results obtained by
running in single-thread and multi-thread mode (say, numthreads i
Thanks very much for your help and your advice.
Are there any publications which describe the principles of the Monte Carlo
simulation when used for correction of multiple comparisons?
