CHECK_ALIGNMENT

      Modeller users:
When analyzing your alignment file using CHECK_ALIGNMENT, how critical
is it to eliminate all of the following errors:
chkaln___> Checking pairwise structural superpositions: 
           Equivalent CA pairs with distance difference larger than 
6.0               
           angstroms:
chkaln___> Checking structure-sequence alignments: 
           Implied target CA(i)-CA(i+1) distances longer than  8.0
angstroms:
Should you keep refining the alignment until all of these errors are
eliminated, or are one or two acceptable (i.e. 6.2 ang., 8.4 ang... )
