insert_from_nwbfile(nwbf, *, nwb_file_name)
classmethod
¶
Add each entry in the NWB file epochs table to the IntervalList.
The interval list name for each epoch is set to the first tag for the epoch. If the epoch has no tags, then 'interval_x' will be used as the interval list name, where x is the index (0-indexed) of the epoch in the epochs table. The start time and stop time of the epoch are stored in the valid_times field as a numpy array of [start time, stop time] for each epoch.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
nwbf
|
NWBFile
|
The source NWB file object. |
required |
nwb_file_name
|
str
|
The file name of the NWB file, used as a primary key to the Session table. |

Interval
¶
Class to handle interval lists
NOTE: methods with -prefix are for internal use comparing two interval lists to allow for inverting non-communicative methods (i.e., AxB!=BxA). External equivalents (without -prefix) runs these methods on self vs other.
