Usage

From source file:eu.eubrazilcc.lvl.core.io.FastaWriter.java

public static void writeFasta(final OutputStream os, final GBSeq gbSeq) throws IOException {

    os.write(header.getBytes());//from   w w  w.  j a v a 2 s . c o  m
    os.write(LINE_SEPARATOR);

    int compoundCount = 0;
    final String sequence = trimToEmpty(gbSeq.getGBSeqSequence()).toUpperCase();
    for (int i = 0; i < sequence.length(); i++) {
