Add a new line after the last file recording

[Wei-HD]

Dear all,

I used ShortRead package to filter the data and then saved as fastq file. But when I run the qa function again there is error in .local(dirPath, pattern, ...): > > ShortRead internal: too many 'snap' entries.

In the bioc-sig-sequencing mailing list, Martin already mentioned it might be due to the missing last line as separator.

But I do not know how to add a new line after the last line in my file. Does anyone give me some hints?

Many thanks in advance!

You could do it in Perl:

open OUTFILE, ">>file.fastq" or die $!; # open for append
print OUTFILE "\n";
close OUTFILE;

Thank you so much nodonb! That works! even I do not know the meaning of each code.
