HELP: some suggestions for SNP discovery in 454?

[linikujp]

I am analyzing the 454 transcriptome sequences.
The big problem here is to detect some differences are SNPs or error base call.

Who has done the similar analysis?
Could you please give me some suggestions? or useful tools?

Thanks a lot!

Best,
Lin.
