Hi all I was trying to run RaxML to draw a phylogeny using like this. But unfortunately I got some error, can anyone please help me out.

$ ./raxmlHPC -s Test_aln -m GTRCAT -n Test -p 12345

RAxML correctly finished parsing your PHYLIP file,
but there seems to be garbage at the end of the file, i.e., non-whitespace characters!
RAxML will exit now

End of the aln file looks like this

GTTCGGTGAG TGGCTCCGCC ACGACATCCT TTCCGGAACG TTCGAGCCTG CCGTTCTGGA
TCACGATCTT GCGATTTTGC TGACCAAGGC GAGGCAACAC AGCCTTGCGC TTCTAGGCCC
ATCCGCAGCC ACGTTTTTCG AGCCGGTGCC GAAGGAGCAT TTCTCCAAGG CGCTTTTCGA
CACTATTGCC CAGTGGAATG CAGAGTCGGA TTGGAAGGGT GACGAGCGGA ACGTCGTTCT

Thanks advance
