Hello, None of our tools should generate this warning - it might be a firefox error - does your firefox browser launch normally? Kind Regards Matthew > Hello, > > When I run my Melodic temporal concat analysis on my 25 files, the reg_standard folder in each subject's folder isn't created. When I ran the exact same process last week on 6 files, it was all fine and ran smoothly. Now, I have re-run it several times and it doesn't seem to create this folder/directory nor does the melodic_mix file appear in the gica folder. Any reasons as to why this is happening? I am getting no errors after the analysis is run except the following : > > addons.productaddons WARN Failed downloading XML, status:0, reason: error > > Thank you for all help. > > Regards, > Shruti >
