Dear CCPN team,

please help me in correcting the following problem:

I have a CCPN project that contains one molecule,
one assignment but multiple spectra and shift lists.

After having worked with this CCPN project for about
3-4 months, I noticed that in the assignment names
(accessible by clicking on the peak and going to the
assignment panel) the atom designator in the name
has been replaced by a number in square brackets.

e.g.
313Gly[3409]

instead of

313GlyH

This is the case in all shifts lists for all
spectra. I first did not notice this as labels in
the spectra are minimal and have only the position
number and amino acid in one letter code. So I
really can't say when this change occurred or what I
did to provoke it. Needless to say the the backup by
that time was corrupt as well.

Any try to assign, reassign, de-assign and reassign
fail without an error message, the labels simply
stays the way it is. Even deleting the peak, picking
anew and trying to assign result in the same missing
atom name as before.

A lot of work has gone into this CCPN data set and I
was hoping you may be able to help me restore the
correct status. Frankly, as a new-bee to using CCPN
I do not even know where to start to look.

I am using CCPN 2.1.5 running on the 64 bit version
of CENTOS5.

Thank you.

Sincerely,

Till Maurer
