Dear Olof, yes, you can avoid running randomise on all components. If you set the number of permutations to 0 in your dual regression call, it will only estimate the time series and spatial maps, without running any test. You can then run randomise separately on the component of interest, giving as input the 4D obtained from stage 2 of dual regression (for the first component it will be dr_stage2_ic0000.nii.gz) Hope it helps, Ludovica — Ludovica Griffanti, PhD Analysis Postdoctoral Research Assistant Wellcome Centre for Integrative Neuroimaging (WIN) Oxford Centre for Functional MRI of the Brain (FMRIB) Nuffield Department of Clinical Neurosciences, University of Oxford John Radcliffe Hospital Oxford, OX3 9DU, UK email: [log in to unmask]<mailto:[log in to unmask]> On 7 Sep 2018, at 11:42 am, Olof Lindberg <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi, I am running the Melodic/dual_regression tools. I am interested only on selected networks which I identify from running Melodic on my control group. I would like to run randomize only on components that I think is relevant to my analysis - however so far I only managed to get the tool to run all (in my case 30 components) Is there a way putting into the commandline for example run component 1 in randomize? thanks Olof ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1 ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
