Hello,

I think you want the macro command call("class.method", arg1,  
arg2, ...) See http://rsb.info.nih.gov/ij/developer/macro/ 
functions.html#C for more info.  The run("command", ...) command is  
used to call ImageJ menu commands which is a little different. Your  
FITS reader plugin will have to have a static method to return the  
contents of the FITS header as a string (or strings that have been  
concetenated into one string) to the macro.

Cheers,
Ben
