Hi,
My underlay is T1, the overlay is a stats map let's say for instance Fstats. I would like to add an ROI shown by box or edge such that one can visually check how well the stats map overlaps with the ROI. This ROI is given by a mask nii. What I could do with @chauffeur_afni so far is to have stats map on T1, stats map on ROI edge using -edgy_ulay, but how to plot these 3 things in one

What almost works is to give the ROI mask in -clusterize -mask, but it will only show the intersection between the map cluster and the mask.

Hello,
I have an ROI defined on anat as a mask nii file, would it be possible to plot this as the box in the alpha+box stats map using @chauffeur_afni? For instance, for the Fstats map in the QC report, F>threshold is highlighted by lower transparency, and the edges of the clusters are highlighted by the box. Is there a way to keep everything the same but only replace the box with the ROI?

Hi Rick,
Thank you very much.
>> What is a typical range of durations?
The range of durations varies from subject to subject since the events are observational, I don't have a summary of it right now. It goes from 0.2s to ~5s, but we group events based on some domain knowledge, and usually events in one type have similar durations.
>> Personally, I tend to round the t

Hello,
May I ask for your recommendation on the appropriate time resolution to use when preparing a task timing file?
In our case, event onsets and durations are defined based on concurrent EEG recordings, and their time resolution is rounded to 0.1 seconds. Should I use this resolution directly when preparing the timing 1D file, or is it better to align them to the TR grid? My understandin

Hello,
I am doing HRF deconvolution using afni_proc.py, the process finished without error but I could not find the output specified by -ireps in the result folder. Could you please help me tackle this issue? Here is the afni_proc.py code
