Hi,
I have a phosphorylated tyrosine in my protein (CCPN code: Ptr). Everything
has functioned correctly, however, if I want to print the secondary
structure chart, analysis complains "could not load reference NMR data for
the protein:Ptr".
The error message is as follows:
=============================================================================
>>> Exception in Tkinter callback

=============================================================================
Is there anyway around this?
Thanks in advance,
