Dear Rajkumar,

Good day.
 
For my current project, I need some bioinformatics support. Please treat the data confidential since we have to publish it.
I have 9 sets of files each with ~10K fasta sequences (Sanger). However, some query sequences are ‘0’ in length (nearly 4% of total 80K reads). For example, please see the following set of 5 sequences where (0) represents absence of sequence data.  
 
>FLXa1302.ePiR_A01 (0)
>FLXa1302.EPiF_A02 (0)
>FLXa1302.ePiR_A02 (0)
>FLXa1302.EPiF_A03 (0)
>FLXa1302.ePiR_A03 (0)
 
I am attaching a file with the mixture of these (0 bp) reads with normal fasta sequences.
I wish to group reads with sequences and reads without sequences into two individual set of files for further analysis. Also, I wish to have subset of sequences which are more than 80 bp in length. I don’t want to delete them. I want 3 subsets from each set of sequences. i.e
 
Reads (0bp)
Reads from 1 bp to 80 bp in length
Reads with more than 80 bp
 
I am attaching the first file. Could you please try to segregate that into three files as mentioned above? Once I get the result for this file I will go through it, then I will send the remaining files.
Thanks for your time,
 
Sincerely,
Raja
