Rotating data axes with nmrPipe

From NMR Wiki

Combinations of functions TP - transpose X&Y - and ZTP - transpose Z and Y - will rotate data. There are also options for xyz2pipe and pipe2xyz that allow data rotation, but perhaps TP and ZTP are easier to understand.

For example, this script will exchange Y and Z axes in 3D data.

xyz2pipe -in ft/test%03d.ft3 \
| nmrPipe -fn TP \
| nmrPipe -fn ZTP \
| pipe2xyz -out ft/rot%03d.ft3
