Origin Version (Select Help-->About Origin): 7.0
Operating System: Win XP
Hi,
I am fitting multiple data sets to Exp decay. I was hoping to save the fitting parameters from all the fits to a single file where each column will give me each of the parameters for fits performed.
I have included the code for reference.
Thanks,
Rahul
[Main]
FDLOG.multiopen.colview=12;
FDLOG.UseGroup(Ascii); //Open ASCII files
if (FDLOG.multiopen()==0/0)
return 1;
loop(ii,1,FDlog.MultiOpen.Count)
{
FDlog.Get(A, ii);
win -t data;
open -w %A;
%W= %H;
win -ch 1;
// wks.colsel(2,1);
run.section(, Plot, %W);
run.section(Fit,EXPDECAY1);
}
[Plot]
win -t plot Scatter G%W;
layer -i %W_b 0201 201;
layer -a;
layer.x.from = 0;
label -xb "Time(s)";
label -s -p 75 50 -n label1 G%W;
label1.fsize = 22; // change font size for label1
return 0; |

The MultiFit add-on on the File Exchange should do what you want. Use the function mf2wks like this...
[Main]
FDLOG.multiopen.colview=12;
FDLOG.UseGroup(Ascii); //Open ASCII files
if (FDLOG.multiopen()==0/0)
return 1;
%O=FitParam; // name of parameter wks (MultiFit will create the wks)
loop(ii,1,FDlog.MultiOpen.Count)
{
FDlog.Get(A, ii);
win -t data;
open -w %A;
%W= %H;
win -ch 1;
// wks.colsel(2,1);
run.section(, Plot, %W);
run.section(Fit,EXPDECAY1);
mf2wks %O; // copy parameters to wks
}

Hi Mike,
Thanks for the tip. But I can't seem to get the multifit add on to compile. It is giving compilation errors listed below:
compiling...
MultiFit.c
C:\Program Files\OriginLab\Origin7\OriginC\MultiFit.c(443) :Error, Variable "" not declared
C:\Program Files\OriginLab\Origin7\OriginC\MultiFit.c(443) :Error, general compile error
C:\Program Files\OriginLab\Origin7\OriginC\MultiFit.c(441) :Error, error(s) found in compiling function mfCreateOutputWks
Could I be doing something wrong? or is it a bug?

Hi Rahul,
Line 443 uses the LabTalk.object feature that was introduced in a service release. I don't remember which SR so I suggest you update to the latest... SR4.
...You can stop the compiler error with SR2 but I still recommend SR4.

Hi Mike,
With the SR4 version, Multifit complies and Labtalk code runs perfectly.
Thanks a lot for help.
