Hi, We are trying to unzip and load dense functional connectome (HCP_S900_820_rfMRI_MSMAll_groupPCA_d4500ROW_zcorr.zip or HCP_S900_820_rfMRI_MSMSulc_groupPCA_d4500ROW_zcorr.zip from https://www.humanconnectome.org/study/hcp-young-adult/article/announcing-release-of-s900-ptn-and-other-group-average-data) in Matlab on a system that has 32 GB RAM. This is of course impossible due to the fact that the files are ~33 GB in size. Due to matrix symmetry, it would be sufficient to store only the upper or lower triangular part of a functional connectivity matrix, reducing memory occupancy by about 50% (Loewe et al., 2016). Does HCP provide such files that could be memory-friendly?
Best, Reza _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
