does any one know how to run a dos command through perl script?
I am trying to run bl2seq command in a for loop-with the inputs beeing 2 Filehandlers.
General syntax of the command is:
bl2seq -p programname -i firstfilename -j secondfilename -o
which in my program is :
C:\\xxx\\xxx\\xxx\\bl2seq\\bin\\bl2seq -p blastp -i C:\\xxx\\xxx\\xxx\\xx\\FH1  -j C:\\xxx\\xxx\\xxx\\xxx\\FH2  -o C:\\xxx\\xxx\\xxx\\xxx\\FH1.txt");
I am trying to call this using system();
Please help me.
