RE: Problem with looking fdr corrected maps
Hi Sounak,
Yes, the pFDR* maps contain the FDR-p values at each voxel (so low values there represent stronger results and high values represent weaker results), so a reasonable way to display these would be to threshold these maps at the desired FDR level (e.g. p-FDR<.05) and then display the resulting suprathreshold mask. You can generate these masks, for example, using spm_imcalc and entering your pFDR*.nii volume and the expression "i1<.05".
Hope this helps
Alfonso

Hello Alfonso and Everyone!!
I am little bothered by how my FDR corrected map looks after my analysis. Mine is a single subject resting state analysis with 4 sessions per analysis. I am attaching the the FDR corrected map (p_FDR<0.005) and corresponding correlation coefficient map (r>0.3). I am visualizing it in MRiCRon. It looks like the FDR correlation map is showing the boundary region of the correlated areas. Is there a better way to visualize it?
Thanks
