It seems that the header files in Pekings data do not mention TR value and slice order sequence. Does anyone else know these values?
It would be of great help to me.

Thanks

Dear Waqas,

I don't know which release you are refering to. I have checked the files I used for the NIAK release and it says the TR is 2 sec. As of the slice order sequence the protocol says interleaved. Check the protocol here:
http://fcon_1000.projects.nitrc.org/indi...

and all info re ADHD200 are here:
http://fcon_1000.projects.nitrc.org/indi...

Also I would advise to post on the INDI forum rather than on the neurobureau forum:
http://www.nitrc.org/forum/forum.php?for...

The INDI collective is responsible for the curation and release of raw ADHD200 data. The neurobureau has only been involved in the release of preprocessed data. Best,
