How to lanuch ITK-SNAP in MATLAB using the system command

[jiancong wang]

Hey guys, 

I am Cong, a student learning image analysis. I am writing to ask how to launch ITK-SNAP and open a nii file in MATLAB? 

I am working on something like 

command='C:\Program Files (x86)\ITK-SNAP 3.2\bin\ITK-SNAP -g baseline.nii';

system(command)

(assuming there is a baseline.nii file in the path). 

I tried the command in command prompt and it works. But in MATLAB with the system function it kept telling me that 

'C:\Program' is not recognized as an internal or external command, 

operable program or batch file. 

It is weird that when I try 

command='C:\Program Files (x86)\ITK-SNAP 3.2\bin\ITK-SNAP';

system(command)

The code works! I really don't know why adding the -g baseline.nii crashes the function. Please help!

You should add double quotes to encapsulate your file names (inside the single quotes) otherwise spaces are confusing for system:

command=' "C:\Program Files (x86)\ITK-SNAP 3.2\bin\ITK-SNAP" -g baseline.nii';

system(command)

I get that too, it seems when there is only one file Matlab automatically adds the double quotes, because, this command does not word in a real command window (cmd).
