Slice timing correction in the UCLA Consortium for Neuropsychiatric Phenomics LA5c Study dataset

Hello, I am writing a thesis on schizophrenia. Therefore, I thought the UCLA dataset would be useful for me and downloaded the rs-fMRI data. I do the preprocessing in FSL. I want to do slice timing correction but I don’t know how slices are imported. Can you help with this ? Where can I find out how to get slices?

Not familiar with this dataset, but are the slice timings not in the bold.json files? Also, FSL by default does not do slice timing correction (see this and this), although other preprocessing pipelines like fMRIPrep do STC.
