Hi I would like to use 'write.fasta(sequences, names, nbchar = 60, file.out, open = "w")' to convert a DNA sequence in a text file to fasta format. How do I read the the text file to prepare the argument 'sequences' of the function. The DNA sequence in the text file is one line as below: ATCACACAACGACACTCACCCTGGACGCTCATC......... Thank you [[alternative HTML version deleted]]
