575. Gaussview: CConnetctionGFCHK::Parse_GFCHK() Missing or bad data: Alpha Orbital Energies Line Number XXXX

I've been getting a fair number of errors when trying to open .fchk files with gaussview 4.x that I've generated using g09. In particular, I've been getting this:

Thinking that it might have something to do with the version of gaussview being too old, I tried gaussview 5.x, which throws the same error. Gaussview (4.x), by the way, runs fine in wine 1.7.

Turns out it's a poorly written piece of software -- gaussview can't properly parse output generated by gaussian. Great...neither piece of software is cheap. Better yet, gabedit does not have any issue reading the unmodified fchk file.

If you do need to use gview though, the solution is outlined here: http://www.ccl.net/cgi-bin/ccl/message-new?2012+07+18+005

Briefly, edit your fchk file and change the "Number of basis functions" to the same number as is shown for the "Number of independent functions" i.e. change
