File pattern#
In order to find the ref file and the darkend files we are using python re library. Here are a fiew example of how to use it:
.*conti_dark.* will filter files containing conti_dark sentence
darkend[0-9]{3,4} will filter files named darkend followed by three or four digit characters (and having the .edf extension)
ref*.*[0-9]{3,4}_[0-9]{3,4} will filter files named ref followed by any character and ending by X_Y where X and Y are groups of three or four digit characters.
To have more example and usage see the re library page.
