NFACT (Non-negative matrix Factorisation of Tractography data) is a set of modules (as well as an end to end pipeline) that decomposes tractography data using NMF/ICA.
- It consists of three "main" decomposition modules:
- nfact_pp (Pre-process data for decomposition)
- nfact_decomp (Decomposes a single or average group matrix using NMF or ICA)
- nfact_dr (Dual regression on group matrix)
- And three auxiliary modules:
- nfact_config (Creates config files for the pipeline and for changing any hyperparameters)
- nfact_Qc (Creates hitmaps to check for bias in decomposition)
- nfact_stats (Creates spatial maps and component loadings for further statistical testing)
- and a pipeline wrapper
- nfact (Runs nfact_pp, nfact_decomp, nfact_Qc and nfact_dr. nfact_pp, nfact_Qc and nfact_dr can all individually be skipped)
