I have read/consulted these two threads here, the ABI file format document, the BioPython project, the R project, the BioConductor project and have searched extensively on the Internet, but I am not able to find an answer or explanation for what I would like to do.
<del>I would like to know how to interpret trace data from an ABI/AB1 trace file and how to plot this data. Ideally, I'd like to plot it on a web-page (in some format that allows for scrolling of course, but I haven't thought that much about this yet), but first I need to understand the trace data itself and how to plot it with Python and/or R.</del>
Edit: I have managed to extract the raw point data from chromatogram files. What approach should I take to plot curves like the trace-viewing programs do (FinchTV, Chromas, etc.) ? After much searching, I've found this and this. Are these the right approach or do I need a spline function?
