PeakTrace is a basecaller and improves your DNA sequences, but will not allow you to view the peaks in the .ab1 trace file. To visualize the trace you need a trace viewing program. There are many good trace viewers and most are free. Many come with additional features like manual editing, BLAST analysis, or the ability to view the raw data.
To help you find the best trace viewer for your needs we have listed all the trace viewers we are aware that exist. We will be adding reviews of the various programs as we find time.
