Dear Randy,
I was wondering if there is any setting that needs to be considered for the rapid event-related fMRI (e.g., the TR of .800 ms for example).
Also, in the FAQ section, the following has been stated:
f you selected "Use HRF instead of Block length", we adopted some feature from SPM. Instead of only using 1 time bin, SPM increases the Microtime resolution 16 times. This may bring some benefit if you input decimal onset time directly, though eventually the length of convolved onsets is still the number of scans (i.e. one scan is still the smallest unit). If you input decimal onset time directly, please make sure that your slices must be in sequential order rather than interleaved order. Also, please make sure that your slices must be in ascending order (i.e. 1st slice is at bottom) instead of descending order or rounding order. Otherwise, you must enter integer for the onset time.

If you use block length, PLS will round the decimals

Thanks alot for your answer.
Would you also be able to let me know if there are any settings that needs to be considered if we are having short TR, e.g., 800ms?
Apprecaite your time,
Best,
