Hi,
I dont use Windows, so my answer has little ambiguity. Bruk2ucsf reads acqu?s
and proc?s files alongwith the 2rr or 3rrr file. BYTORDP is a XwinNMR
parameter for indicating byte order. Check the procs file, you might see
something like ##$BYTORDP= 1.

Please give absolute path for the 2rr file and make sure you dont have any
symbols in folder names.

Something from the Sparky manual which might make the difference:

###########
Converting Bruker processed spectra to UCSF format

If you process your data with Brukers XWinNMR or UXNMR software you can
convert it to UCSF format using the program bruk2ucsf supplied with
Sparky. This program has not been tested much. Bruker processed data can
also be read directly by Sparky. Both the Bruker and UCSF file formats
store the data matrix in blocks so that the whole file does not need to
be brought into memory. The Bruker blocks are typically large (1Mb) while
the UCSF blocks are small (32Kb). Because Sparky is designed to use the
small blocks, you might run out of memory if you have many Bruker spectra
loaded simultaneously. In this case you should convert the Bruker files
to UCSF format with bruk2ucsf.

To convert Bruker processed data 1/pdata/1/2rr to UCSF format use:

% bruk2ucsf 1/pdata/1/2rr noesy150.ucsf

###########

Try the data conversion and let us know,
regards

hello....Im starting using sparky and its very slow (really slow)
refreshing the spectra window when you do any manipilations such as
zooming.

I read the 2 dimension files (2rr) as I do in NMRview or Auremol using
same PC (windowsXP-SP2). The graphic card is decent Nvidia 6800 GT.

Comparing sparky spectra manipulations seems to take forever compared
with other above programs.

There is anything that you recommended or that I should have done in
order to have good refreshing rates?

Thanks in advance:
PP
