I am having problems reading the CTF .hc headcoordinates file

The most likely problem that you have with your CTF dataset is due to a bug in the dataset itself. Old versions of the CTF acquisition software would write the .hc file with a typo in the file. The file itself is an ASCII file which you can open in any text editor.

The 5th line in the file is

ā€™ā€™ stadard left ear coil position relative to dewar (cm):ā€™ā€™

but should be

ā€™ā€™ standard left ear coil position relative to dewar (cm):ā€™ā€™

Note the missing ā€œnā€ in the problematic .hc headcoordinates file.
