Running this recipe on Puzzle 139 or 140 results in FoldIt immediately quitting as it tries to apply the "add bands" step:

Remove all bands
Add bands between all residues
Wiggle for 1 iteration
Remove all bands

==> The "Example 3: compression" recipe works for me, however, as does a modified version of this script (which asks for bands to be formed between all selected residues). With these in mind, is the crash due to an out-of-memory error? Or is it because I somehow went over the limit of rubber bands that could coexist at the same time?

[For a 150-residue protein, banding every pair would give 150 * 149 / 2 = 11,175 bands. Note that manually selecting 75 residues and banding all of them, which gives 75 * 74 / 2 = 2,775 bands, does NOT crash the program.]

Thanks for reporting, it does sound like it could be related to the number of rubber bands. We'll look into it.

Bump. This issue still occurs today if one tries to run a recipe/script that bands every nth residue if the protein is very long (typically, that means length/n > 70 for my laptop); it would be nice if the program could cancel the batch banding operation if it can't be done for any reason (e.g. not enough memory).

Just not create zillion bands... :P
