Hi all, I have a 2D Bruker dataset that took a while to acquire, so I'd rather not simply repeat it. However, it seems I mis-set a parameter before acquisition. The pulse sequence changes a pulse length through the use of a loop counter and I need to set the IN_F parameter to the length of the loop before acquisition. That was incorrectly set, so the result I get in the F1 dimension does not make sense. I only really need the F1 FT of a single row.
Thanks, Mark UPDATE: I have figured out how to export and reprocess the F1 dimension of one column in IGOR, so answers to #2 are no longer needed. If, however, you can provide guidance on how to reset F1 scaling after acquisition, I would appreciate it. asked Jul 21 '13 at 19:38 wilsonmv |
Hi, I had a similar problem in some HSQC where I filled in wrong parameter before acquisition. Your parameter IN_F or whatever is an acquisition status parameter and is read from acqus (or acqu2s) file. Editing this file externally should fix it. Close Topspin (or at least switch to another experiment), correct the value in acqus or acqu2s by vi or other text editor and reread the spectrum.
