Hello. There are programs of all kinds for online bioinformatics analysis (blast, alignments, dotplot, phylogenetics, genetic diagnosis, etc) so I would like someone to explain why it is necessary to know some programming language (python, perl, C +) in the field of bioinformatics. What tasks can we perform through a programming language that can not be done in a program that we have online? Can you give me some examples? Thank you very much.
