Dear all FSL experts
I want to apply the temporal concatenation ICA and dual regression analysis on the rsfMRI study with relative large sample size (> 1000 participants). Due to the limited memory size and computational capacity (I only have PC with 32G ram), I try to use meta-ICA approach to deal with this large dataset currently. After reading the interesting paper "Group PCA for very large fMRI datasets", I realize there are at least two novel approaches (MELODICs Incremental Group-PCA and Small-Memory Iterated Group-PCA approach) could also deal with this large dataset, but unfortunately I am not good at writing code to perform such analysis. Could some of the FSL developers provide these wonderful codes for me to perform Group-ICA and dual-regression analysis on this large dataset.
