Many folks have been uploading images of spectra but the website was not specific about where it was going to take a slice to graph. Now there's a note on the upload page. This will be helpful for spectra like:
However, even more convenient (although still pretty shabby in interface) is the button you'll see below your spectra now which lets you "set sample row". This has a terrible interface but we'll be revising the whole spectrum view page for a new "analysis page" soon -- the important part is that you can enter a row # and it will sample your image at that # of rows from the top. So the following spectrum suddenly has data, whereas before it was reading the black data from the top row of the image:
I also fixed the profile page link and made some other small tweaks, including adding a blog link to the top, which just leads to the Public Lab website and shows all research notes tagged with "spectralworkbench". That way I can write updates here.
I haven't had a lot of time to write code recently but don't worry, we have a lot of big plans for the software and things should be getting much easier as we go!
