COMPILLATION:

You can compile the program as easy as

g++ dnapunctuation.cpp -o dnapunctuation

To accelerate processing time one can try these parameters (essential when annotating large chromosomes):

g++ -O2 -march=native dnapunctuation.cpp -o dnapunctuation

Here, the executable version was compiled under Mac OS High Sierra, version 10.13.6


RUNNING:

The program takes 7 arguments:

  1. imput sequence file in fasta format
  2. Minimum size of a stem
  3. Maximum size of a stem
  4. Minimum size of a loop
  5. Maximum size of a loop
  6. Number of mismatches allowed

One should run the program as

./dnapuncutation L1.fna 6 15 3 10 1

where L1.fna is a sequence file containing L1 human transposon

6 is the minimum size of a stem 15 is the maximum size of a stem 3 is the minimum size of a loop 10 is the maximum size of a loop 1 is the number of gaps/mismatches allowed

The promram output is the text tab-delimitted file named according to the stem-loop parameters specified as input: L1.fna.S6-15_L3-10_M1.pal

L1.fna and L1.fna.S6-15_L3-10_M1.pal can be found in the main directory
