USAGE:
$ notfound base_directory search_string
This is a simple script designed to help identify subjects that do not yet have a specific file generated. For example when adding new patients to a study. It is designed to be used when each patient has a folder containing their images.
For example:
$ notfound study_folder fod.mif
will identify all subject folders (e.g. study_folder/subject001, study_folder/subject002, ...) that do NOT contain a file fod.mif
Note that this can be used in combination with the foreach script. For example:
$ foreach $(notfound study_folder fod.mif) : dwi2fod IN/dwi.mif IN/response.txt IN/fod.mif
