v5.3.0 nu.mgz, -1): could not open file
by Bondarenko M. 06 Dec '13

06 Dec '13

Hi I am trying to Install Freesurfer V 5.3.0 on a cluster in Southampton University but when I run a job on the cluster it always fails. I have checked all configurations files, I have looked to your manual many times but still can not figure out the problem. Could you please help me out with installation. cat $FREESURFER_HOME/build-stamp.txt => freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 -- which mri_convert => /local/software/rh53/freesurfer/5.3.0/freesurfer/bin/mri_convert I have included my bash script to run a job and also output file. I am getting the error: " mghRead(/home/mb4/test/free/track2010FS/21655/mri/nu.mgz, -1): could not open file mri_em_register: could not open input volume nu.mgz. " I have also try to run "fixup_mni_paths" but it did not help. I have installed FS V4.0 and I did not have such a problem. Could you please have a look to my output and give me some advises. Regards, Max

Dear Rujing, After recon-all and qcache, for correlation analysis, I have performed qdec by using a matrix that contains NPS test, 3 nuisance factors and one groups.For groups analysis I have applied mri_glmfit as described in the guide. Nothing in particular.

In the paper I have 3 groups (2 diseases and 1 controls). I have performed cortical thickness analysis among groups, individuating relevant difference in the posterior regions. Next, for one group, I have used qdec to individuate statistically significant regions where NPS test scores and thickness were correlated. 3 nuisance factors was also added to regressor. All results were corrected for multiple comparisons by using a pre-cached cluster-wise Monte-Carlo Simulation. qdec analysis results have individuated a "composite region" (superior parietal cortex and precuneus) where NPS correlated with thinning. Now, if I understand, I should extract the mean thickness from superior parietal cortex and precuneus and I should perform a linear regression (and partial correlation) with an other statistical program (SPSS for example). Is there a better way to perform a regression the most possible similar to qdec computation?

Hi! All, We ran into a few cases which the wm matter surface is pretty decent but pial surface did not go far enough to include all gray matter. Is there a way to fix this?

nuisance variable in qdec
by Cat Chong 05 Dec '13

05 Dec '13

Dear Doug, Thank you for your instantaneous response! Correcting for disease burden was actually a reviewer comment. We calculated mean cortical thickness estimates for regions that showed vertex-wise age-related cortical thickness differences between groups (using qdec) and then graphed out the slope aging-patterns between normal controls and patients, by extracting the data into SPSS. Basically, our findings indicated that for selected regions, the patients showed a steeper age-related decline. It was suggested by the reviewer to correct the correlation between age and cortical thickness for disease burden in the patient group (using partial correlations in SPSS). Would this be an alternative way? It would sure safe us from re-running our data:) Very Best Regards, Catherine

nuisance variable in qdec
by Cat Chong 05 Dec '13

05 Dec '13

Dear FreeSurfer Experts, We are trying to run a between group analysis (1 patient group 1 control group) within qdec. We are interested in investigating age-related thickness differences between groups. Our fixed factors are ‘group’ and our continuous covariate is ‘age’. We would like to control for other possibly confounding variables which should be declared as “nuisance factors, is that correct? Here is our problem. We like to put down “disease burden” (years subject has had the disease) as our nuisance factor, since it is likely possible that this has an effect on cortical thinning in our disease group. Yet, when we run the model, qdec crashes. Is this because the subjects in the control group have a “0” as disease burden? Could you advise us on another way of controlling for disease burden? Cheers, Catherine
