Hi All

I searched if there is any thread regarding biojava NoClassDefFoundError, so here I am creating one. I am doing multiple sequence alignment using Pyro_align and I ran into this error.

Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/db/SequenceDB
    at SAPNA.main(SAPNA.java:80)
Caused by: java.lang.ClassNotFoundException: org.biojava.bio.seq.db.SequenceDB

I tried with latest to old versions of biojava.jar files and I still get this error. Anyone please suggest me why I get this error?

this is very close to being off topic - it seems that either there is a problem with your class path or the code is incorrect - but I must say this is not really bioinformatics - your best bet is to contact the developers directly.
