Mel Script not Running on 2016 .. OK on Maya2008-2015

I have an Old Mel Script that a grad student wrote back in 2009. It has worked with every Maya version up to 2016.

It is a sphere packing script that allows you to put a ratio into a GUI that then packs the mesh you have selected around a sphere of a given radius.

(It looks up sphere packing ratios found in a directory that you tell the script to source)

The GUI is loading correctly and it finds the directory and the correct ratio (in other words if I tell it pack smaller spheres with radius .5 around a sphere of radius 1 it finds the correct ratio file in the directory of .5 etc)

BUT it gives an error....

Small Radius: .5 Big Radius: 1 Ratio: 0.5 best Guess: of 0.52573111194898 ratio.// Warning: file: /Users/peta/Desktop/spherePacking_Script.mel line 34: fopen: unable to open file "/Users/peta/Desktop/SPratios0.52573111194898.txt" for mode "r". //

I went to line 34 in the script and it says.....

$packingFile = `fopen $packingFileName "r"`;

I checked the permissions of the directory and the files inside it they are all -rwx for everyone.

So I do not think it is a ownership issue. I am on a Mac running El Cap with maya 2016 SP4

I tried the same script on a PC running windows 10 and it is hanging on a different issue that I am unsure how to solve just to test it on a PC to see if it is a Mac thing. The Windows machine is Win 10 and has a space in the User's name so teh mel script looks for C:\Users\Name Name\Desktop\SPratios and hangs on that line

I replace the space with an _ but it did the same thing. So I can't test it on the PC

Obviously mel is not my strong point Thanks for any help. The script is a lifesaver on creating Micelles and Vesicles so any help would be

great.

Thanks Peter

I have attached the script and the appropriate directory that the script searches.

On Windows, the path needs quotation marks around it because of the space character.

I'm not sure about the Mac problem. I know you said the script works on previous versions of Maya. Were you using these same exact data files?

Thanks I will try the quotes and see if that works.

Yeah exact same files as previous
