Hello everyone, I am new on MATLAB and today I try to reproduce the demo given on Bioinformatics toolbox namely "Investigating the Bird Flu Virus". But whenever I used 'featuresparse' function as given in the demo it returns "Undefined function or method 'featuresparse' for input arguments of type 'struct'". same error appears with some other functions as well (viz. 'getgenbank' function). Maybe it's a too simple question to ask, but I am totally clueless. I am sure anyone of u will help me in this. Thanks in advance.

Uptal, You can also try the following:

restoredefaultpath; matlabrc

then see if that corrects your problem.

It sounds like the Bioinformatics Toolbox is not installed on your machine, or not properly installed.

If you enter


at the command prompt, do you see the Bioinformatics Toolbox in the list of products?

Also, does the command:


return a 1, or 0?

featuresparse appeared in the toolbox for R2006b and has been there since. If you are using that version or newer, please use


to check whether it thinks you have a license for the bioinformatics toolbox, and please use

which -all featuresparse

to see whether it can locate the file.
