That looks like a loop from one of the SALIGN example scripts, which simply calls SALIGN three times. If you look further down in the script you will see this: aln.salign(..., feature_weights=weights)
i.e. SALIGN is being called with the weights given by the first argument in that 'for' statement above.

They're weights - just numbers that multiply each feature's distance matrix. The distance matrix used by SALIGN is simply a linear combination of these.

I mean exactly what it says - that's elementary Python syntax. *6 is the same as saying [0,0,0,0,0,0]. In other words, all of the features will have zero weight, so SALIGN won't calculate any of them.
