Hi Andy,

Thank you for the reply.
Earlier problem was I had not applied the compliment in the ChromatoGraph.
Now I could inspect the alignment with the Phrap calls

Please refer :  http://i43.tinypic.com/e5iu12.png

I have drawn orange underlines from where the two sequences matches.
But I had to hardcode x1 and x2 offset values to make the graphs align 
with the Phrap basecalls.
So as for my question 
http://lists.open-bio.org/pipermail/biojava-l/2009-June/006707.html , if 
somehow get all (or fill) all the callbases same as in ACE , I can align 
easily.


Best Regards,
Umanga
