@jat255 So I did not have this problem. See the images below. I set the 50th and 100th spectral bin to be identically 0 at every image pixel. Note the...

Here's a more intense example (I randomly killed half of the channels). Just for info I used: ``` # Just a copy of my hyperspectral image data hsi2 = 1*hsi...

@jat255 > I don't believe HyperSpy is doing anything unusual, but I will try to reproduce using only `pyMCR` and not HyperSpy to make sure I see the same behavior......

@AndrewHerzing @jat255 * How many SVD components are you keeping? * Make sure the input spectra (into MCR) have positive values? * If you all want, you can send me...

@AndrewHerzing @jat255 Sorry for my delay: was off in the woods hiking Fri-Sun. I'll be curious to see why things are failing as it's not obvious to me.

@aminsagar Thanks for the question! I'm not 100% familiar with the row- and column-wise data augmentation in the MCR-ALS package. * Do you have further information on what that means...

@aminsagar Great description. I can see possible ways to implement it -- let me check into that. I'll see what I can do to make that happen. Do you have...

@aminsagar Sorry it's going to take a bit to implement this: just busy with work. If you have any coding expertise and want to take a crack at it, feel...

> > > @CCampJr @aminsagar > > Is there any follow-up/new information on this issue? @HaasCP I haven't heard anything. Are you, too, interested in this?

@HaasCP Gotcha. This package is a lot more flexible (matrix augmentation withstanding) than the MATLAB one because one can choose any algorithm for regression and constraints are easy to implement....
