Recently I was asked by one of the professor to solve problem in FORTRAN. I am already working with PERL, PYTHON, JAVA, C and C++ but now I am thinking "Is it worth to learn FORTRAN in bioinformatics?" Please suggest.
I am thankful to every one who commented and gave their valuable suggestions. In the end, after learning FORTRAN for two weeks, I concluded, learning too many languages will messing up everything for me in the end. Hence, I decided not to work for the professor who was asking me to learn FORTRAN and will start again looking for professors who works in the similar field as mine.
Thanks everyone for their valuable suggestion and detailed insight.
This has already been asked here. As alluded to in the answers, Fortran is still used for numerical libraries (and not just BLAS/LAPACK) that are wrapped in other languages. It is still used in bioinformatics fields that do heavy numerical computations such as molecular dynamics and structural biology. Programming languages are just tools so one should go with the one most efficient for the task at hand (efficiency here also includes proficiency in the language).
