25 Mar 2014 plot crosshairs A gui interface for reading (x,y) values from line plot(s). Author: Darren Weber Filip Ligmalej

Excellent job! However, when I click to place where multiple lines overlap (e.g. same data plotted twice) an error appears at line 430 "Error using set - Value must be a column or row vector". I've traced it to interpY function which on line 479 calls NearestXYMatrixPoint function with probably wrong result for yindex not being single value. From this point everything goes bad I thing, but maybe I've missed something. But thanks anyway for such a nice piece of code.

29 Nov 2012 MRI Analyze tools Read/View Analyze data format (MRI). Author: Darren Weber Layla

I have been trying to use the avw_img_read function to read in the eigenvalues and eigenvectors from a Diffusion Tensor Image. I appended 12 of these files (3 files for eigenvalues, 9 for eigenvector components) into a single volume in Analyze before exporting it as a .hdr and .img file for use with this code. That is, there are 12 224x224x65 files appended into one. This code doesn't seem to recognize that--the result is instead just one 224x224x65 double (labeled 'img' by default) in the avw struct. How can I get the code to recognize the other 11 data files in that one .img/.hdr file?

17 Nov 2011 Mesh Laplacian Interpolation Operator Computes the zero Laplacian interpolation matrix Author: Darren Weber Timothy

This program is a hidden gem. I am able to interpolate on a meshed surface with an index of scalar values.

The only problem that I was running into (I wrote a code for it) is that the program sorts the nodes list but does not keep the scalar value for the specified nodes. Example of this: 2 3 1 have values of 0.3 0.2 and 0.5, the list is sorted as 1 2 3, but the values remain as 0.3 0.2 0.5 and not 0.5 0.3 0.2. Also when removing the same points, you also need to remove the reiterated scalar values.

Thank you very much. Great Code, saved lot of time.
