26 Oct 2009 GSTools A set of matlab functions to read, write and deal with .spc spectra and spectral descriptions Author: Kris De Gussem Bowles, Cameron

I found an error for opening multifiles using GSSpcRead.m.

line 437 is;
data = zeros (l,Specdata.spectra(1).data);

and it should be;
data = zeros (l,length(Specdata.spectra(1).data));

Other then that I have had no problems, a great piece of code, good work Kris

fixed-point signed fractions,

I ran into one last problem, the exponent values in the headers/subheaders are in char form, meaning that if they are between 129 - 255, then they are actually between -127 to -1, or at least they are in the files I am reading in.

this causes the Y-axis to be incorrectly scaled, the fix I put in for this is in GSSpcRead; line 689, I inserted the following check loop at 689;

if YScalingExp > 128
      YScalingExp = YScalingExp-256;
end
 then the file should continue
CurrSpec = ........

I assume the process would be the same for the 16 bit input integers, in which case you would have to also put that check into line 675.

fantastic bit of code, works better than the old GRAMS converter ive been using until now!

Just downloaded it to convert SPC Raman data and it works perfectly! Noted a small error in the manual on page 2: plot (SData.xaxis, data);
doesn't work, just change to:
plot (SData.xaxis, Sdata.data); and it works fine.

Use it for importing multi-dimensional spectra: and it works perfect!

I needed to import SPC files and it works immediately.

Haven't used it for .spc files, but it includes an easy to use BTree class. Note that the @BTree\private\DoCompare.m method will fail upon unsigned types unless you replace the line

     tmp = item - value;

with

     tmp = (item > value) - (item < value);

I have only used this for reading in an .spc file. It worked great. It even plots the spectra so you know it was loaded properly.
