In Chimera beta 1 build 2199 on Windows XP Professional SP2, I cannot open a FASTA file that contains a single sequence. (The file in question is attached and looks to be a valid FASTA file according to the documentation I have read on the FASTA format.) What should I do about this issue?<br />
<br />
Error log:<br />
