Different naming convention

[MonaMehrabani]

Hi, Thanks for your work.
I have been using this package. When I call the cfile2pixels function to return a list of pairs of img_arr and contour_arr for a given contour file, I'm getting this error: FileNotFound

[Errno 2] No such file or directory: '/content/drive/MyDrive/MRIplusGd-with-Contour/1.2.840.113619.2.388.10502719.2140823.14003.1697945075.89.dcm'

The contours are in the RTSS file format, while the MRI images in my directory are named like "IMG0000000000.dcm". However, the function looks for images with a different naming convention.
How can I resolve this problem?
