Hi, The HCP S1200 Reference Manual says that there are two versions of 4 movie files. Some subjects have been scanned with one version, and the remaining subjects have been scanned with another version. Version 2 includes these changes:
7T_MOVIE1_CC1_v2 remains unchanged. 7T_ MOVIE2_HO1_v2 removed 1 frame of rest before the validation clip. 7T_MOVIE3_CC2_v2 removed 5 frames of rest before the validation clip. 7T_MOVIE4_HO2_v2 added 4 frames of rest before the validation clip. Here *frame* is a frame of the movie, right? Assuming that the movies are ~25 frames per second, the deviations are between 0 and ~200 ms in each movie file. Considering the TR of one second and the slow hemodynamic BOLD responses, these deviations are negligible, and we can possibly ignore them when concatenating time-series data across all subjects. Would you agree? Thanks, Reza _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
