Also some confusion here:
(2) Header is NOT allowed in a one-column input file, but is optional for a multi-column input file: If provided in the first row, it has to be the labels of those ROIs/nodes, as the format of data frame in R. ROI time series as input are required, but covariates are optional. All ROI time series can be stored in one data frame, or multiple one-column files, but not a mixture.
BUT when you run the program:
[1] "Header with one line of labels is allowed in one-column files, but NOT in multi-column files."
ROI time series data type (0: MULTIPLE one-column files; 1: ONE multi-column file)?
I'm assuming the program is correct?
