Fixed time resampling

AFNI Message Board

Hi the AFNI team,

I'm curious if there's an AFNI tool that performs fixed time resampling for time series data.

To give you an idea, I have a 2D+time dataset where images were captured at various time points(e.g. 0, 55ms, 101ms, 155ms, ...) and I'd like to resample the dataset so that each image is uniformly spaced at intervals of 50ms.

Thanks a bunch in advance!

Hi, Vu-

3dUpsample is probably the ticket:

ps: I couldn't actually remember the name of the program, but I searched for 'upsample' on this Classified Programs page, and that got me there.
