SPACI score report for 1bwm in ASTRAL 1.57:

WARNING! The SPACI score for this entry is not valid. This is not an X-ray structure, so the resolution and R-factor listed may be arbitrary and not valid. The resolution is not available. An arbitrary resolution has been used. The R-factor is not available and an abitrary R-factor has been used. The WHAT_CHECK parameters for this entry could not be obtained, and poor results have been arbitrarily assumed.
