Step - 1 :
Excecute createFasta4COVID.m in order to generate refFasta files for each miRNA with 
reference genome.
Execute createAlignFile.m file in order to align miRNAs with reference genome.
Execute generateSeqScore.m file in order to get the score of aligned mi-RNAs.

Step - 2
Excecute merging-alignments-and-score-generation.py for merging the alignmnets
and region selection along with the score generation for the miRNAs belonging to 
each region.
