is something wrong in it 59

at this webside First I downloat it inhome-rita-downloads then i use tar command as tar xzvf programname.gz and then i made a folder called MFOLD athome-rita and in .bashrc file i wrote export MFOLDDAT=-home-ritu-MFOLD

no ,I am just thinking, i write rita....pollyrita$ mfold then i get bash:mfold:command not found though i am expacting to run this command.

then i tried type mfold i get bash:type:mfold:not found though i am expacting path .

after that if i change directoryhome-rita to downloads and write mfold again i get command not found

but if here i write .-mfold i get Usage is mfold SEQ=`filename' with optional parameters: AUX=`auxfilename' RUNTYPE=text (default) or html NA=RNA (default) or DNA LC=sequence type (default = linear) T=temperature (default = 37¡) P=percent (default = 5) W=window parameter (default - set by sequence length) MAXBP=max base pair distance (default - no limit) MAX=maximum number of foldings to be computed (default 100) ANN=structure annotation (default = none, p-num or ss-count) START=5' base # (default = 1) STOP=3' base # (default = end) REUSE=NO-YES (default=NO) reuse existing .sav file

then i tried .-mfold SEQ='filename' i get cat:home-rita-MFOLD-begin.dat3: No such file or directory REUSE= NO .-mfold: line 1: reformat-seq.sh: command not found auxgen failed Job Aborted

How I can Run this Command? Thanks
