output sICA components
Hi -

I ran NIAK pipeline with CORSICA successfully and I was wondering if it is possible to specify to the pipeline that I would like to have access to sICA components from CORSICA in the outputs.
Is there any way to do this?

Thank you very much!

RE: output sICA components
Dear Cécile,

There are actually two ways of doing that.

1. The brutal way. Just set :

opt.size_output = 'all';

You will keep every single intermediate output of the pipeline, including the time/space components of the spatial ICA. This will also keep all the fMRI datasets at every possible stage of preprocessing, which may not be what you want.

2. The specific way. Set :

opt.corsica.size_output = 'all';

This parameter will impact only the CORSICA pipeline. This means that you will keep the time/space components of sICA, but not any of the intermediate preprocessed fMRI datasets. Note that this parameter can be used even with "opt.corsica.flag_skip = true;" because the CORSICA method is still applied even if you skip it, for quality control purposes. It's just that in this case no component is actually removed from the datasets.

Best regards,

Pierre
