wobble |
For each of the six possible translation frames, this plots a graph showing the percentage of 'G' and 'C' bases in the third position of codons in the frame within a window that is moved over the sequence.
Bases other than 'G' and 'C' can be chosen with the -bases option.
The Mean of the third base percentage value is drawn as a horizontal line across the plots.
Here is a sample session with wobble. The example sequence is from Pseudomonas aeruginosa, which has a high G+C content and a very biased third codon position (if it can be G or C, it usually is).

"Specifying ACG&T is meaningless" - When you use the option -bases to specify the bases to look for, it is pointless to specify looking for all the possible bases as these should add to 100% all the time.
"No bases specified" - Similarly you have to specify some bases to look for otherwise you must plot a 0% line.
