Batch Curve Fit Syntax Error

Hi All,

I have a 2D wave, each column is a Y data set and a single 1D column wave as the X data.

The wave scaling of the X-data is not regular and i'm not too sure how the machine made the divisions. So if it is possible to scale every column to in the 2D matrix to the X-data set of strange unknown irregular scaling that would be great and possibly avoid the following problem.

When batch curve fitting I try and use the following settings:
Y from 2D wave columns, X from a single 1D wave
I get the following "Error on batch 0: syntax error" on every column.

BUT
If i use the same parameters (masks, functions and coefficients) and use
Y from 2D wave columns, X from wave scaling the curve fitter works fine...but if i fit a gaussian then my x0 and width will be wrong. Ideally i'd like to export the table of txt and further process those values.

Any ideas how to proceed. I think the easiest solution would be to somehow wave scale the whole 2D wave with the 1D wave but i'm not sure how to do it.

Thanks,

N
For the masses who will undoubtedly come here looking for a solution to their similar problem, the issue turned out to be that the x wave was 2D. It had only 1 column, but that was enough to make the CurveFit operation reject it. The biggest issue, from my perspective, is that Batch Curve Fit did not produce meaningful error messages. Igor Pro 7 and the next release of Igor Pro 6 will have the improved error reporting.

Thanks Nate for your help!

If someone else does have similar problem make sure your waves are 1D if not you can re-dimension them.

Good luck,
N
