Origin Version (Select Help-->About Origin): origin 7.5
Operating System: winXP
hi, all, i have multiple data files (81 files) and want to deal with them in the same way. is there a simpler way to do it, for example, a function which can record the data process and all i need to do is to replay it to all the other files?
here is the first file. i need to calculate the area ratio of the peak on th left to the one on the right in each file.
thanks a lot.
all the bests

Origin has no macro recorder but programming your processing steps is straightforward. If you can import your files with the Import ASCII routine then the following LabTalk script will import, plot, integrate and report areas to the Results log for as many files as you choose. You can run the script from the Custom Routine button.
getnum
(Start 1) i1
(Stop 1) i2
(Start 2) j1
(Stop 2) j2
(Enter peak indices...);
FDLOG.UseGroup(Ascii);
if (FDLOG.multiopen()==0/0) return 1;
savered=type.Redirection(16,3);
type.BeginResults();
type "Peak1: $(i1) --> $(i2)";
type "Peak2: $(j1) --> $(j2)";
type "File\tArea1\tArea2\tA1:A2";
separator 4;
loop(ii,1,FDlog.MultiOpen.Count)
{
FDlog.Get(A, ii);
win -t data; // new worksheet
open -w %A; // import
%W=%H; // save wks name
FDlog.Get(A,ii,1); // file name without extension
win -t plot; // new graph
layer -w %W 200; // line plots
integrate -a %C -b i1 -e i2; // integrate peak 1
a1=integ.area; // save area 1
integrate -a %C -b j1 -e j2; // integrate peak 2
a2=integ.area; // save area 2
type "%A\t$(a1)\t$(a2)\t$(a1/a2)"; // type results
plot -c; // refresh graph
};
separator 4;
type.EndResults();
type.Redirection=savered;

Thanks very much for the helpful reply, but could you please tell me how to index a peak in the Labtalk script. I'm just a beginner at Origin, not very sure about the right way.
thanks in advance for your kind help.

The indices are just the row numbers between which you want to integrate. You can use the Data Reader tool on a sample data plot to determine the indices.
