Hi -
The missing JAR file is the jakarta regular expression library (required in biojava1.3 not required in biojava-live). You can get it from the biojava download page.

Hi, Good day!
I got a "NoClassDefFound" exception when I call:
db = SeqIOTools.readFasta(is,alpha);
-----------------------------------------excert from my code--------------------------------------------------
import java.io.*;
import java.util.*;
import org.biojava.bio.*;
import org.biojava.bio.seq.*;
import org.biojava.bio.seq.io.*;
import org.biojava.bio.seq.db.*;
import org.biojava.bio.dist.*;
import org.biojava.bio.dp.*;
import org.biojava.bio.symbol.*;
import org.biojava.bio.seq.Sequence;
.....
//setup file path + name
String fileName="..\\input.txt";
BufferedInputStream is = new BufferedInputStream(new FileInputStream(fileName));
//get the appropriate alphabet:DNA,RNA, or PROTEIN
Alphabet alpha = AlphabetManager.alphabetForName("PROTEIN");
//get a sequenceDB of all sequences in the file
db = SeqIOTools.readFasta(is,alpha);
.....
-----------------------------------------error message---------------------------------------------------------------
java.lang.NoClassDefFoundError: org/apache/regexp/RESyntaxException
