Running Fiji script in python

Question

I am trying to get a home made Fiji script to sun inside Python by calling Fiji, but there's little documentation on how to do it. What I need is something like this:

 def myfijiscript:
 [CODE]

and then in Python:

 fiji(myfijiscript)

is there a way to do this?

• hivert: I guess you mean def myfijiscript(): with parentheses. What's the problem with simply calling myfijiscript() (after importing what is needed of course) ?
• Samuele Mattiuzzo: I assume you checked fiji.sc/Scripting_toolbox#Python this link and it's not what you want, right? ;)
• koldrakan: yeah, I did, and it's great for writing the script I want to use. Calling Fiji to run it from within Python, however, is where the problem is

Answer 1

Python (or, to be precise, Jython) scripts within Fiji are executed using the org.python.util.PythonInterpreter class (see source code).

It doesn't make much sense to run a Jython script within a Java instance that is started from with Python, but have a look at those two questions concerning how to run external commands in python. You can save your script in a file myscript.py and then do:

call(["./ImageJ-linux64", "myscript.py"])

using the ImageJ launcher from the command line.

The other way is to use ImageJ as a library and just import the classes you need for your script, as others have suggested:

from ij import IJ
