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
download
the updated one at
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mris_preproc?
We also have some people using FreeSurfer 5.1.0, mris_preproc release date
5-17-11, Revision 1.59.2.1. Do they need to update their mris_preproc
script?
Thank you very much,
Jeff Sadino
Hello,
Is it possible to covary for a categorical variable in QDEC? I see other
posters have said it is not possible, but I did not see
any official documentation or response regarding the issue.
Thank You,
