Dear experts,
I am attempting to assess the effects of age on vertex-wise grey/white-matter contrast, after regressing out effects of sex and vertex-wise effects of thickness using the -evperdat flag.
My setup for the left hemisphere is as follows:
# Configuration file for PALM.
# Version alpha105, running in MATLAB 8.3.0.532 (R2014a).
-i path/concat_n1467_lh.contrast.10.mgh
-evperdat path/concat_n1467_lh.thickness.15.mgh 4
-s path/freesurfer_5.3.0/subjects/fsaverage/surf/lh.white
-T
-tfce2D
-logp
-d path/age_reg.sex.thick_design.csv
-t path/contrast.csv
-n 10.000
-o path/lh_contrast_fsaverage.10.age_reg.sex.thick
-demean
-fdr
-“i” is a single .mgh file containing 1467 concatenated contrast surfaces
-“evperdat” is a single .mgh file containing 1467 concatenated thickness surfaces
My design matrix contains 1467 rows and 4 colomns (1st for male, 2nd for female, 3rd for age and a 4th which is a dummy variable for thickness containing 0’es (I have also tried other values here).
My contrast is as follows:
0,0,1,0
0,0,-1,0
The error I receive is :
{Error using zeros
Out of memory. Type HELP MEMORY for your options.
Error in palm_core (line 615)
plm.Hz{y}{m}{c}{o} =
zeros(N,N,size(plm.Mset{m},3));
Error in palm (line 81)
palm_core(varargin{:});
}
I was wondering if this really seems to be a memory problem, or if more likely, I have set it up incorrectly? Thank you all so much in advance!
Kind regards Linn Norbom
