Details

raveio_setopt stores key-value pair in local path. The values are persistent and shared across multiple sessions. There are some read-only keys such as "session_string". Trying to set those keys will result in error.

The following keys are reserved by 'RAVE':

data_dir

Directory path, where processed data are stored; default is at home directory, folder ~/rave_data/data_dir

raw_data_dir

Directory path, where raw data files are stored, mainly the original signal files and imaging files; default is at home directory, folder ~/rave_data/raw_dir

max_worker

Maximum number of CPU cores to use; default is one less than the total number of CPU cores

mni_template_root

Directory path, where 'MNI' templates are stored

raveio_getopt returns value corresponding to the keys. If key is missing, the whole option will be returned.

If set all=TRUE, raveio_resetopt resets all keys including non-standard ones. However "session_string" will never reset.
