This file is required to run the compare m6A app.

It is a simple text file with one position (number) per line, indicating which nucleotides should be modified to m6A.

Example: For a sequence with m6A modifications at positions 23, 27, and 39, the file should contain:

23
27
39

Important notes:

• Positions are numbered starting from 1 (first nucleotide of your sequence)
• The script will check if each position corresponds to an 'A' - if not, it will be skipped
• All positions must be within the sequence length - the script will validate this and show an error if any position exceeds the sequence length
• Only positions that are 'A' will be modified to m6A
• The file should contain only numbers, one per line
