Good to know, thanks!

Hi Paul, hi Niels,

PALM removes the NaN and Infs before starting so this shouldn't be the issue. However, depending on the values in the data, design and/or contrasts, new NaNs or Infs can be created during the analysis, leading to that error. One possibility is that the test is assessing whether the group mean is different than zero, which is always the case for GM volume, leading to statistics that approach infinity, then the error.

Paul: could you show your design and contrasts? Thanks.

All the best,

Anderson

What do you get if you run fslstats -R on your input image and mask?

Hi

The input data file and the corresponded mask file were also run through fslmaths with the -nan option before entering into the PALM software , but the error still occured.

Hi. I haven't had this issue myself but it sounds like you might need to run your input image through fslmaths with the -nan option.

Dear PALM developers

I tried to perform permutation test for our VBM dataset (we use SPM for VBM preprocessing) using PALM software. After running permutation test, the error message comes out in the MATLAB command window. Could you help me to deal with this error message ? In addtion, although the error message occured, PALM still produced s2_ILAS_1197_vox_tstat.nii for each statistical contrast.

I use the following command for PALM analysis (We use the latest version of PALM and Matlab R2012a.). The s2_GM_1197.nii contains 1197 subjects VBM preprocessed dataset.

palm -i /mnt/HD2T/PLAM_statistic/S2_GM_1197/s2_GM_1197.nii -m dartel4_mask.nii -d statistic.mat -t statistic.con -f statistic.fts -T -C 2.58 -n 1500 -fdr -save1-p -accel tail -o /mnt/HD2T/PLAM_statistic/S2_GM_1197/s2_ILAS_1197

The following message is error message :
