this is not bioinformatics and is not a tool and as such it is off-topic on this site
Instead of simply posting a chunk of code it would be useful to add a line or two to say where this could would be useful. Not immediately apparent as to what area of bioinformatics this is applicable to.
Hello friends,
Thank you for your feedback. I understand that the post may not directly relate to bioinformatics. My aim was to share a useful script for converting Degree Minutes (DM) to Decimal Degrees (DD), which can be relevant in geospatial analysis of biological data. I appreciate your guidance and will ensure future posts align better with the forum's focus.
