Hi all,
I loaded a pseudo3D 15N T1 Relaxation HSQC into CCPN. I have several remarks and questions regarding the Relaxation analysis in Analysis:
1) when I load the delays from Brukers vd-(variable delay) list, Analysis does not recognize the units. In the 'Experiment:NMR series' menu there is a '?' for the unit and I cannot change it to something else. Still, fitting the data works perfectly. Is it bug?
2) Is there a way to exclude one or several seriespoints? The 'Delete Series Point' button in the 'Experiment:NMR series menu' is not clickable...
3) Once I fit the Relaxation data, I can exclude datapoints for individual fits in the 'Fit Graph'-window: however, there is no button to undo the deletion. Refitting the data using 'Group & Fit Peaks' or 'Re-fit All Groups' included the data again, but did this for all residues.
4) I would like to extract the Intensity for a given peak at the exact same position along the entire time axis. This position should be at the average of the peak maxima of one peak along the time axis (as proposed by d'Auvergne). However, whatever I tried, I did not manage to keep the position of the peak fixed in the 'Group & Fit Peaks'-routine of the 'Data Analysis:Follow Intenstiy Changes' menu. Furthermore I could not specify individual peak lists to the HSQCs in the pseudo3D.
5) Is there a way in Analysis to calculate the delays for a T2 Experiment from the vc-(variable counter) list for the CPMG field in Topspin?
I hope these were not too many questions :-) CCPN Analysis is a great programm, thanks!
Dominic
