CE-MC trouble shooting

CE MC is decent software. But have to be careful about its input and output.
Problem 1.
local running or picasso running good, while sometimes running in NODE fails.

Problem 2.
input format. After my logic comparison, the problem:
DETERMINING MASTER STRUCTURE BASED ON Z-SCORE
Id:0 1XVA:A, average Z-score:0.000
Id:1 1R8X:A, average Z-score:0.000
Id:2 1R74:A, average Z-score:0.000
Master structure is: 1XVA:A(highest average Z-score)

None of the structures have average Z_score above the threshold
>>>>ERROR: FAILED to run mc

mostly is due to the format of input pdb-format file. In the data/ folder, file pdb1xva.ent
must begin with the first line : HEADER ................3X' '1XVA(3 spaces+pdb_id).
That's the only difference between accepted format (have non-0 Z-score) and failing format.

Problem 3.
Output PDB-file, after the Chain ID, PDB require 1 space+ 4 digit residue number + 1 iCode + 3 space
before the X coordinate(8 digit max). Depending on different machines, the space between chain ID and
residue number can vary from 0 to 2. Careful when you parse the output structure file.
