Thank-you all for any help. I am doing the analysis of patch-clamp data.
Basically I need to know the basics on how to use the lab-script language.
All I want is to be able to do the same analysis on different sets of data that
I import as asci files, from PCLAMP of AXON instruments.
I always have the same number of rows and columns, and always need to do the
same mathematical fit.
Is there anyway I can configure the system so that I can have a template in
terms of graph parameters
(such as range of data to be fit, axis configuration, and that the boltzman
function can be passed to my data without having to specify each time the same
parameters?)
I import a multi file using the pclamp6 module, do a substraction between two
columns(using all the rows), plot the result, filter it, and pass a fit that I
have configured.
Some problems :
1) I have configured a function and when I start the fitting, the function
always gives me a horizontal line, no matters how I initialize the parameters
What could I do about this?

2)In order to inter/extrapolate, how can I do it? I am performing a linear
regression and I want to extrapolate but as I do so, the resulting line is
always a horizontal line.
I am using origin 4.1 version,with 16 and 32 bit installation, and for those
in the area, I am doing IV plots, followed by activation/inactivation curves
for sodium currents in rat brain...
Thank-you for the help

RE: LabTalk Scripting Help

Following is a summary of the questions you have asked. 

Is there anyway I can configure the system so that I can have a template in terms of graph parameters such as range of data to be fit? 

The range of data to be fit can be set by using the variables MKS1 and MKS2. MKS1 is the starting row number and MKS2 is the ending row number. For example, if you have 100 datapoints, but only want to fit rows 10 though 85, use the following:

MKS1=10; //Set beginning of range
MKS2=85; //Set end of range

Axis configuration?

Axis configurations are saved with graph templates. You can set the properties of the graph such as colors, layer size and location, text labels, plot types, axis rescale properties, and many other properties. Once this template has been saved, you can open the template with the LabTalk commands window -t or page -t.

Can the boltzman function can be passed to my data without having to specify each time the same parameters?

To perform the Bolzman sigmoidal fitting, you can use the following command:

run.section(fit,Sigmoidal); //performs a sigmoidal fit on the current data selection

If you want to set the default parameters for the Bolzman function, go into the fitfunc subdirectory of Origin41. Open bolzman.fdf with a text editor. You can now edit the Initial Values line.

A short script which would use these features would look like:

window -t templatefilename.otp; //open template
layer -i Data1_B; //Add dataset to layer
mks1=10; //set begin range
mks2=85; //set end range
run.section(fit.Sigmoidal); //run sigmoidal fitting script

Please send a detailed description of the problems you are having with a horizontal line appearing to our tech support department at tech@microcal.com .
