Thomas, you just need to adjust a few more parameters. For phase sensitive data make sure that ph_mod is not set to mc or ps, but pk or no. The apodization function WDW probably also needs to be set.

Hi Thomas, assuming this is phase-sensitive data, you want a cosine rather than a sine window function (i.e. window function starts at 1 and goes to zero, rather than starts and ends at zero). The SINE window function uses the value of the parameter SSB and has the form:

SINE(t)= sin( (PI-PHI)*(t/AQ) + PHI)

where PHI = PI/SSB, and t runs from zero to AQ.

If SSB = 1 (or 0), this is a sine finction, if SSB=2 this is a cosine function. For phase-sensitive data you want the cosine function, or you will get odd looking data, sort of "antiphase" and thus a bit like DQF cosy. I would also use the QSIN (squared sine/cosine) window for phase sensitive data, but it's the SSB value that's more critical. This should be 2 in both dimensions.

The sine window function with SSB=1 is used to narrow the base of the broad lines in magnitude-mode spectra - for magnitude mode data use WDW=SINE, SSB=1 and PHMOD=MC in F1, PHMOD=NO in F2.

Hope that helps!

Topspin has a command vconv that imports the varian data. Once the data file is imported, you can do the usual topspin processing.

A minor issue we found is that sometimes the quad detection mode is set incorrectly for the multidimensional experiments, which can be adjusted in the eda window.

Hi I am using Bruker Tpospin for brain spectroscopy analysis. I am new to this software. My question is how do I make spectral lines dotted or thicker instead of colors. Any hint is highly appreciated. Thanks Surya
