Hi Bruce, This problem is in spite of rotating it.

Invisible flattened cortex
by SHRIKANTH KULASHEKHAR 14 Mar '08

14 Mar '08

Hi, I am trying to flatten the lateral and medial sections of the brain. The flattening processes using mris_flatten -w 0 12 work fine without any errors. And I am able to visualize the flattened medial portion. However, when I load the flattened lateral portion the window is blank with no errors. I can visualize the patch created for the lateral section though. Any ideas on what could be wrong ? Thank you, Shriks Forgot the famous last words?

analysis of covariance using qdec
by Narly A Golestani 13 Mar '08

13 Mar '08

Dear all, Does qdec allow analyses of covariance, and if so, how? is it possible for example to test the effect of a regressor while controlling for the effect of a particular measure? thanks, best, Narly.

How to analyze fMRI data with mixed design?
by Zhen Zonglei 13 Mar '08

13 Mar '08

Dear, Dr. Greve: I hope I don't bother you too much. But I'm wondering about how to analyze mixed blocked/event related design with FSFAST. In our experiment, we have two blocked conditions and three event-related conditions in every block. We are not sure how to write the parfiles and construct the model to analyze these data in FSFAST. Please give us some suggestions on this issue. Thanks in advance. Zonglei Zhen

pre-processing, glmfit, and multiple comparisons
by Nicolas Cherbuin 13 Mar '08

13 Mar '08

Hi, Although the documentation for fs is fantasic there are a few questions I have not been able to answer to my satisfaction. I hope somebody will have some patience left to help me out :-) 1. When using mris_preproc we must provide an fsgd file, it is not clear to me if and how the information in the fsgd file is used in this step. Since this file is required I assume that it is not possible to preprocess the data once with a generic fsgd file and then perform glmfit with different fsgd files but just in case I thought I'd check. 2. Next to the FDR rate in the configuration overlay window there is a "only marked" tick box. How is this meant to be used? 3. I have searched the mailing list and the web but I am still a bit confused about what strategy works best in practice for mutliple comparison correction. My experience so far is that if I use FDR most results disappear.... Thanks Nic

A problem in analyzing DTI data with dt_recon.
by Zhen Zonglei 13 Mar '08

13 Mar '08

Dear, Dr. Greve: Thanks for your help. Today, when we tried to run the new function of FS in DTI analysis, we got stuck again. The dt_recon command cannot run successfully, and always report us 'MRIresample(): error inverting matrix'. The data is from Siemens Trio 3T system, and has 64 diffusion directions. Before running dt_recon, we have unpacked the DTI dicom data to a specific directory with unpacksdcmdir command. To provide more details, I attach the dt_recon.log file and a DTI image (one direction) to this mail. Please help us again. Thanks again!

measuring insula?
by Bird, Anne 13 Mar '08

13 Mar '08

Hi, My research group is interested in measuring the insula but can't find any direct references to it in the freesurfer wiki. Can one obtain data on the insula using freesurfer? If so, how?

Dear FS-Experts, I am trying to run Freesurfer on a Ubuntu 7.10 (Gutsy Gibbon) system and unfortunately I encounter the same problem that Gonzalo Sanchez Benavides and also William McGarry described in earlier emails. Copying the new fsgdfPlot.tcl into the $FREESURFER_HOME/lib/tcl directory stopped the "FsgdfPlot_IsWindowShowing" error but did not save me from getting the other two error messages: /ERROR: In

/But still the error messages do not want to disappear... Any idea where my mistake might be? I am not sure if this is of any relevance but I have added "setenv XLIB_SKIP_ARGB_VISUALS 1" to my SetUpFreeSurfer.csh as without it I was not able to open Qdec at all. Best wishes and thanks a lot in advance, Christian
