[Chimera-users] addH: Weird results

Hi George,
	Chimera 1.6.1 is giving some of the added hydrogens 5-character atom names, which is wider that the allowed field width for atom names in PDB files and therefore the field gets filled with asterisks.  I will try to get this fixed soon and will send mail again when it is.  The fix will only be in the daily build though, unless and until we make a 1.6.2 build.

The result of <file1.pdb> was not reproduced. The errors described above were repeated (see <file2.pdb>). Trying to renumber the atoms according to <file1.pdb> did not help.
