Appending Values to a Table

Share icon

I am new to Igor and I am having a problem with programming.
My problem is I am calculating a value "integral" for several curvefits and I want to append those values into a column in a table. Please help and Thank you!


Menu "Macros"
"2D Guassian Fit...", My2DGaussianFit()
End
Function My2DGaussianFit()
	Variable L, H
	Variable ii
	Prompt L, "Enter Lowest Tw Value:"
	Prompt H, "Enter Highest Tw Value:"
	Variable xmin, xmax, ymin, ymax
	Prompt xmin, "Enter xmin value: " // Set prompt for x param
	Prompt xmax, "Enter xmax value: " // Set prompt for x param
	Prompt ymin, "Enter ymin value: " // Set prompt for y param
	Prompt ymax, "Enter ymax value: " // Set prompt for y param
	DoPrompt "Enter Parameters", L, H, xmin, xmax, ymin, ymax
	if  (V_Flag)
	return -1 // User canceled
	endif
	for  (ii=0; ii<(H); ii+=500)
		string  waveselection= "avg" + num2str(L+ii)
		Wave ws= $waveselection
		Wave w1
		Wave w3
		
		Display; AppendMatrixContour ws vs {w1,w3}
			ModifyContour $waveselection labels=0
			ModifyContour $waveselection autoLevels={*,*,35}
		CurveFit/NTHR=0 Gauss2D ws[xmin,xmax][ymin,ymax] /X=w1[xmin,xmax] /Y=w3[ymin,ymax] /D
			wave W_coef
		
			Variable integral
			
			if  (waveExists (W_coef))
			
			integral= W_coef[1]*2*pi* W_coef[3]*W_coef[5]*sqrt(1-W_coef[6]^2)
			
			Print integral
			endif
	endfor
End

I added formatting to your Igor code per http://www.igorexchange.com/node/3221

My 1st problem is I am calculating a value "integral" for several curvefits and I want to append those values into a column in a table.

You need to create a wave using Make and then append data to it. For example:

Wave/Z/D integrals	// Look for integrals wave in current data folder
if (!WaveExists(integrals))
	Make/D/N=0 integrals
endif
Wave integrals
Variable numPoints = numpnts(integrals)
integrals[numPoints] = {integral}	// Add new point to integrals


After you have created the integrals wave you can display it in a table.

My second problem is I want to remove the labels from my curve fit and "ModifyContour fit_w labels=0" does not remove them.


I'm not sure what the problem is. Your code should work if the string variable waveselection contains the name of the contour. You can use a Print statement to verify this.

Try it manually by choosing Graph->Modify Contour Appearance and selecting None from the Labels popup menu. This will show you the command you need.

hrodstein,
I tried using your code for appending values to table but I am getting an error message of "Inconsistent type for a wave reference" for the Make/D/N line.

Also I did figure out how to remove the labels from my curvefit.

Thanks for your help!

Igor is being excessively picky.

In the first Wave statement add /D after /Z. That will make it happy.
