'Not Parsed' means that the calls within the sequence have not successfully passed thru the parser. That is, the program does not understand all the calls.

'Not Proofread' means that the program did not successfully proofread the choreography in the sequence.

If you wish to proofread the sequences in CSDS, from the main menu, select 'Sequence | Proofread | Specify'. Sequences will automatically be parsed as they are proofread.

If the first line of a sequence is a comment such as (ROT-31 22-Jul-2009 Not Proofread) you can edit the sequence and remove the line.
