VMD Plugin: atomselect error when running protein with negative resid numbers

[lindseymriggs]

I get the error below when running blobulation on 3zbd.pdb: https://www.rcsb.org/structure/3zbd

atomselect: cannot parse selection text: resid -4 -3 -2 -1 0 1 2 3 4 5 6 11 12 13 14 15 16 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 46 47 48 49 50 51 52 53 54 55 56 57 58 59 98 99 100 101 102 103 104 105 3 4 5 6 11 12 13 14 15 16 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 46 47 48 49 50 51 52 53 54 55 56 57 58 59 98 99 100 101 102 103 104 105 and protein and canonAA
