@Josiah,

It shouldn't... (uses str2num or str2double...)
anyway, could you send me a sample file so I can take a look at it?
28 Apr 2012 bmorph - binary morphological transforms Fast binary erosion and dilation, with even faster iterative calls. Author: tudor dima

@Alexander
The structuring element is passed to this function (or to imdilate/imerode, that is).
I am not sure how is it done in Matlab (it's a .mex, twice wrapped :-))

What I suspect it makes the interpreted bmorph to run faster than the MEX is that I do a contour detection on both the image and the strel, then only update those values, the strel is not swept across the whole image.

Until now it only allowed symmetrical strels, but I have recently posted the new version which fixed this. (Thanks to Sean Sklios for the provided test data and also for the push!)

Hi, Marcos
Check if your current location (where you installed this toolbox) contains any spaces. (it happends on Windows, .../My Documents/ ...)
If this is the case try to move it to a space-less location.
If for some reason this isn't possible try this hack, until I post the new version :

Replace line 307 with cd(attData.myData.loc.ImageDir)

@Marcos
This box uses Matlab imread.m, I suspect you could find a Dicom reader on the exchange and either plug it in or convert your images to .jpg, .png, etc.

Be careful with blank spaces in your directory, though, the error above seems to stem from there. I am planning to allow this in a future release.
08 Nov 2011 Inpaint over missing data in N-D arrays Y = INPAINTN(X) replaces the missing data in X by extra/interpolating the non-missing elements. Author: Damien Garcia

Great work, extremely useful, it works out of the box.
Thanks a lot for posting it!

Would there be a simple way to restrict calculations inside a "gating mask"?

I'm finding an issue with SXPWrite.
It does not support or properly truncate scientific notation- a number like -9.8235e-5 ends up being written to the file like -9.8235. This is a HUGE problem! Otherwise a great set of tools.

You warned me about blank spaces in a previous comment but I forgot it, thanks again.
