PC: A sample fMRI data in .rda format.

In PGICA: Parallel Group ICA Algorithm

Description

This is a subsample of real fMRI data from the 1000 Connectome Project.

Usage

data(PC)

Format

PC is a 30000 by 20 matrix, where 30000 is the number of voxels in brain.

Details

This is not the original data, but the data after a dimension reduction(from 67749 by 100 to 67749 by 20) using PCA. Then a sample of 30000 voxels are picked out of 67749. The sample is achieved by setting the seed to be 0.
