Hi everybody!
I'm trying to run RNAfold.exe with the matlab system command.The command line call is as follows:
RNAfold -p -d2 --noLP -P dna_mathews.par --noconv < sequence1.fa > sequence1.out
I tried to obtain the same in matlab using the following code:
[status, result]=system(['RNAfold.exe <', 'sequence1.txt'], '-echo');
It works but only partially. I can input the system with the correct file but not the specified options such as for example the parameters that should be used (e.g. dna_mathews.par).
I would like to know if it's possible to only input the file but also the options. Can anyone help me with this?
Thanks in advance!
Iene

Did you try the whole string that is used in Command line
system('RNAfold -p -d2 --noLP -P dna_mathews.par --noconv < sequence1.fa > sequence1.out')

Thank you for you answer but unfortunately yes and the error is:
Error using system
Unrecognized option: -p -d2 --noLP -P dna_mathews.par --noconv < sequence1.fa > sequence1.out

Try this:
1. Put this line into a text file called input.txt
-p -d2 --noLP -P dna_mathews.par --noconv < sequence1.fa > sequence1.out
2. Run this in MATLAB
system('RNAfold < input.txt')
