Hello,
I am interested in running VBM analyses using the TFCE toolbox/CAT12 and am new to using both. I understand from the others posts in this thread that we first:
1. run our design in SPM
2. estimate in SPM
3. define contrasts using SPM results
My first question is if we apply certain options for running the results in SPM before using the TFCE toolbox? For example, masking = none, then should we choose FWE or uncorrected? If uncorrected, should we go with the defaults p<.0001 and put in our value for extent threshold for voxels?
I tried running the TFCE analyses and can see that we can choose FWE, FDR, or uncorrected when viewing results, but I wasn't sure if we should choose certain options in SPM-results before running TFCE estimation.
Another question I had with the TFCE toolbox is that it states I can choose more than one contrast to estimate, however when I do so, I get an error message "Error using isempty
Too many input arguments." Am I doing this the wrong way?
Also, reading through the other posts it seems we can run repeated measures ANOVA with TFCE, but not using the flexible factorial design in CAT12. So can it be done through through SPM 2nd-level analyses instead?
Thank you,
AV
