[SasView Users] [SasView Help] Error Message when loading 2D data

[Paul Butler via users]

Hi Kuo-Chih,

2D data formats are very specific (unlike 1D which most people default to
the same general format).  now that the NeXUS NXcanSAS standard reduced
data format has been approved, we are trying to encourage its use to avoid
exactly this kind of problem.  Bruker poeple have attended some of the
canSAS meetings where the standard work was discussed and now that it has
been approved I encourage you to ask them to output their data in said
format.

In the meantime, for legacy reasons only, SasView also supports the NIST 2D
ASCII format.  Further, as you discovered, SasView has a converter which
will convert ISIS 2D ASCII format as well as the BSL/OTOKO 2D format.
Question: What type of ASCII format are you getting from Fit2D? My guess is
that the error is because the format is not a supported input format to the
converter? I am assuming this error is being thrown when you try to convert
the data? I am well aware of Fit2D but have never used it so not sure what
2D output formats it supports, but looking online I'm not sure that its two
ASCII 2D outputs (Spread sheet and MCA) are compatible?  It seems like
Fit2D will output a BSL 2D? which the SasView converter should be able to
handle.  It also seems to output a TIFF. If all else fails you can try that
and use the image converter to see if it works?

There maybe others who know more about the Fit2D output who might have some
suggestions.  Otherwise please let us know how you get on and if I have
misunderstood the problem please don't hesitate to ask again.

Cheers

Paul
