Hey, I am working on matlab R2009A on ubuntu 11.04. Using the deploytool, I generated a test package for a matlab code of mine. Afterwards, I installed MCR using the command
sudo ./MCRInstaller.bin
which installed it at /opt/MATLAB/MATLAB_Compiler_Runtime/. Now to run the program, I extracted the package and then ran the file run_test.sh using command
./run_test.sh /opt/MATLAB/MATLAB_Compiler_Runtime/v710/ 10 128
where 10 and 128 are the arguments to the main function in the package. It gives me the error as
??? Error using ==> phantom>parse_inputs at 107
Unknown default phantom selected.
Error in ==> phantom at 69
Error in ==> MLEM at 3
Images:phantom:unknownPhantom
MLEM is my main program and at line 3, I have used the phantom function as
i = phantom(SIZE)
SIZE is an input argument(=128 in this case)

Hi Sabya,
just a guess: you know that input parameters to standalone applications are always passed as strings? This can be handled e.g. by
function myfunction(x,y)
if ischar(x)
x = str2double(x);
end
if ischar(y)
y = str2double(y);
end
Or using isdeployed instead of ischar ...

I put the following statements in my code
if(ischar(SIZE))
SIZE=str2int(SIZE);
end
Still no use, same error crops up.

Hi Sabya,
where does the str2int function come from? Or did you mean str2double? What I sometimes do in these cases: I add after the first line a
save c:\temp\inputVariables
so that all input variables are saved. Then run the compiled application. Then load in MATLAB the variables
load c:\temp\inputVariables
and call your MATLAB function with just these variables to see what happens ...

You cannot pass just a size to phantom(). The first parameter must be either a string or an array.

No, thats not true. The function phantom works perfectly when run the code normally from matlab command line.

I mean that the command
i=phantom(256)
work perfectly storing a 256x256 image in i

Does it work with 128 as the input argument when run in MATLAB? The error is coming from phantom>parse_inputs, and is not a standard MATLAB error, so it's hard to tell what could be going wrong without looking at your code. Perhaps putting some DISP statements in phantom>parse_inputs will help with debugging.

the code woks fine when i execute it from matlab prompt as
MLEM(10,128)

Passing only a size to phantom is not a documented syntax in R2009a.

I don't have the license associated with my account; so i can't view the above page. But the code is working in my system perfectly from matlab command prompt.

The R2009a documentation page is formatted differently than the current documentation page but contains the same information as the current (R2012a) documentation -- with no documented possibility of passing only a size.
If you insist on using undocumented behavior and your code fails, then we cannot be of assistance to you.

Hi Walter,
don't know about R2009a, but in R2012a the doc contains the following "example":
% ph = phantom(256);
% figure, imshow(ph)

Hello there, anyone would provide me an MLEM algorithm for image reconstruction? Thank you
