Dear Professors, I am pretty new to task fMRI data and I would like to check how to use the files in the EVs folder to extract information from the .dtseries.nii file for the MOTOR dataset. As an example I chose subject 100307 with the LR phase and I was able to build this table from the files in the EVs folder:
type start time (s) countdown 0 cue_rightHand 8.05 rightHand 11.009 cue-leftFoot 23.164 leftFoot 38.291 So suppose I would like to extract from a .dtseries.nii file (having 284 rows x 91282 grayordinates) the part of the time series corresponding to the Right Hand task listed above. Then: Should I pick all the rows covering the time interval [11.009;23.164] ? If so, should I pick rows 15 through 33 from the .dtseries.nii file which cover the time interval starting from 10.8 (=0.72*15) until 23.76(=0.72*33) ? Moreover, does the same interpretation hold for obtaining the .dtseries.nii rows corresponding to the cues and the fixation blocks? Thank you very much, Javier Zapata --------------------------------- PhD Student UC Santa Barbara _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
