Issue with merge_mctal #32
Description
I've discovered an issue with merge_mctal regarding collapsing, if we collapse two mcnp produced mctal files (eg mc1 and mc2), then we get a file which looks an awful lot like a mctal file. Which is good.
However, if we have 4 mtctal files mc1,mc2,mc3, and mc4, then if no matter how we combine these four files, eg
mc1+mc2 => comb1
mc3+mc4 => comb2
comb2+comb1 => mc5
However, I cannot run merge_mctal on comb1 and comb2, it fails with an error when reading these files, suggesting that the format is not quite right.
Error Reading comb1.: ('invalid literal for float(): 1.00000e-07s',)
I can send you the problem files if you want?
