- Import files (Advanced view)
- import and select one or more wig files
- import and select a bed file
- click 'convert selected'

Bug:
- The generated pwig files appear in the list of the wig files
- The filenames of the generated pwig files contain backslashes instead of slashes, resulting in a long filename instead of indicating the path of the file

How to solve:
- Find out where the backslashes '' are introduced in the filename, replace them by slash '/'
- Ensure that the pwig files are added to the list of pwig files and not the list of wig files
