is_valid_pv_file(file_name)
|
|
Returns bool indicating if the file appears to be a valid pv file.
This function with throw an exception is the file is not a valid
Maestro structure file.
The checks for this are simple, and may not be conclusive. The test is
content, and not file-extension based, since there are valid PV or EPV
files that lack any indication that they are PV files in the file
extension. If you need to check the extension as well see
fileutils.is_poseviewer_file.
A PV file has exactly one structure with a true value for
b_glide_receptor.
An EPV file has one or more structures with a true value for
b_glide_receptor at the beginning of the file. Single-receptor EPV files
are therefore considered PV files, but not EPV files with two or more
receptors.
- Parameters:
file_name (str) - path to the structure file - Returns: bool
- bool indicating if the file appears to be a valid PV file
