When the processing script has:

nmrPipe    -in test.fid \
... usual X axis processing ...
| nmrPipe  -fn TP \
| nmrPipe  -fn COADD -cList 1 -1.1 -time \
...

We have a normal spectum:

But when the processing script has this:

nmrPipe    -in test.fid \
| nmrPipe  -fn COADD -cList 1 -1.1 -axis Y -time \
...

The data looks like so:

I'm a little confused - I thought that -axis Y switch on coadd is equivalent to "transpose, then apply COADD, then transpose again"

I'm a little confused - I thought that -axis Y switch on coadd is equivalent to "transpose, then apply COADD, then transpose again"again"? What is the difference between the above two ways of COADD'ing?

Thank you!
