run cwas pipeline with cpac with already preprocessed fMRI data

[사회과학대학/박수진]

Hi, cpac experts! 

I am so relieved to find this forum and want to ask a few questions.

I am trying to run CWAS pipeline thru cpac and I already have preprocessed (by fMRIprep) fMRI data.

I tried to figure out what I should do to run CWAS pipeline but having a hard time 

understanding overall steps (what to do first, second and so on).

I have created data_settings.yml and data_config.yml files. 

So, I guess it's time to select my pipeline that will run cwas without any preprocessing steps.

this page told me to add the following lines to my file with appropriate paths. 

runCWAS = [0] cwas_roi_file = '/path/to/cwas_mask_file' cwas_regressor_file = '/path/to/cwas_regressor_file' cwas_regressor_participant_column = 'ID cwas_regressor_columns = ['FIQ', 'VIQ', 'PIQ'] cwas_permutations = 500 cwas_parallel_nodes = 3 

I want to make sure where exactly should I add these lines since I don't need any preprocesssing. I thought cpac gui will make my head clear but the page somehow reports an error (Something went wrong!) everytime I try to acccess. 

Is it okay to manually create and run pipeline.yml that only contains the upper lines (since I don't need any preprocessing steps) to run cwas?

And I found MDMR workflow developer documentation where there are 2 relevant source codes (CPAC.cwas.pipeline & CPAC.cwas.cwas). 

I want to check if I should run CPAC.cwas.cwas first and then run CPAC.cwas.pipeline (seems like the latter is run with input from the former) and that if that's all for cwas analysis. 

So, I wonder if there's anyone who can explain sequential steps to run cwas in this case...

I'll be so grateful for any of your help.

Thank you in advance. 

Susan.
