I am planning to use MEGAN. I am currently reading around to prepare. I have come across that MEGAN takes fasta files but have to have the sequence length in the ID line. Mine don't. I asked a friend who did this type of analysis some time ago and said it wont matter. But I just want to double check that MEGAN will take my fasta file without the sequence length. Did anyone every come across similar problem before? I am doing it from the command line.
