Volume 1: A User’s Guide to NMRPipe
Processing a 1D Spectrum
- Overview
Processing a 2D Spectrum
- Overview
- Start the program
- Orient yourself
- Convert Varian’s fid to an NMRPipe fid
- Read in the NMRPipe-format 2D fid.
- Process the first increment
- Edit the script “process2d.com”
- Execute the script “process2d.com”
- Read the spectrum “test.ft” in the NMRPipe GUI
- Phase the F1 dimension
- Edit the script “process2d.com” again
- Re-run the script “process2d.com”
- Convert the NMRPipe file “test.ft” to NMRView format
- You’re done!
Processing 3D Data
- Convert the data
- Process & phase the first plane.
- 3D processing with 2 scripts, LP in 15N only
- Processing 3D data using one script with LP in 13C and 15N
- Examine your 3D spectrum
- Convert the 3D nmrPipe spectrum to nmrView format.
- You are done, done done!
Appendix 1: Phasing
- 1D phasing
- 1D Phasing theory
- Phasing indirectly-detected dimensions

Viewing and Plotting a 2D spectrum
- Presumptions
- Start NMRView
- Orient yourself
- Set Preferences (optional)
- Create a new window

Picking and Assigning Peaks in a 2D spectrum
- Call up the peak picking window
- Adjust the appearance of your spectrum
- Select your peak picking parameters
- Pick the peaks
- Orient yourself with the Peak Panel
- Save your peak list as an .xpk file
- Couple multiple peaks that should be one peak
- Manually add and/or delete peaks to/from the peaklist
- Compress and Degap
- Manually assign residue identities to your peaks (optional)
