A simple application named flfasta to filter FASTA files based on sequence length (minimum or maximum).
You need a compiler capable of compiling C source-code written in at least the C89 standard. For GCC, the compilation can be done with the command gcc main.c -o flfasta.
Execute the application flfasta to see the usage manual.
flfasta (Filter by Length FASTA) version YYYY.MM.DD.micro.
Created by Felipe Ferreira da Silva.
Usage:
flfasta [1] [2] [3] [4] [5]
1: Path to input file.
2: Path to output file.
3: Minimum length.
4: Maximum length (0 to ignore maximum length).
5: Show progress (0 for no, 1 for yes).
File input must be in single-line FASTA format.
For example, executing flfasta input.fasta output.fasta 300 0 1 will generate a file output.fasta containing only the sequences from input.fasta that are longer than 300. Since the argument of maximum length is 0, this there will be no filtering based on the maximum length. The application will output the progress because the final argument is 1.
