TENTs of noninteger width?

Hi all,
I am using a multiband EPI sequence with a TR of 1.4 sec, but I want to do an FIR analysis. For the “TENT(b,c,n)” function, does the width “c” have to be an integer value? The 3dDeconvolve command runs with a non-integer value for “c,” but I wanted to know whether there are any rules regarding the width parameter. At present, I’m thinking of something like ‘TENT(0,15.4,12)’, which would provide an integer number of TRs in the TENT and would include the start and end of the TENT.
Thanks,
Matt

Hi Matt,

There are no restrictions on that, either as being an integer or even as a multiple of the TR.
Sure, your example looks fine.
