Good evening Sir/Madam,

I am currently using CONN toolbox (v. 16.b) via MATLAB to perform resting-state analysis. Once in the Setup, one of the fields required to be filled is the repetition time (TR) -- my experimental value is 2300ms. This is where I have several questions.

First, I was wondering whether I have to simply put "2.3" or whether I have to round it up to "2"/"3" to avoid the decimals? Secondly, in case I should write the decimals, should I use a point or a coma? Third, if I have 100 participants, do I have to put "2.3" hundred times with a space between these values? Lastly, would writing "2" (default value) or "3" (very frequently entered value) instead of "2.3" significantly change the results in the end? I looked in the manual, but couldn't find the answer to my questions.

Thanks!

Sincerely,
