Hi Ted,

If I understand your situation correctly, you have a high level wrapper which does something like

Code:

for (i = 0; i < Abs(fileList); i+=1)
{
	     filePath = fileList[i];
	     treeString = myTrees[i];


	    MPISend (nodeID, "mid_wrapper.bf", {"0":filePath, "1": treeString});
}

 

and you then mid_wrapper.bf makes other lists and passes them to other analyses.

Whatever you pass to MPISend as the third argument list is handled the same way as the call to

Code:

ExecuteAFile ("mid_wrapper.bf", argument)
 

would be in a non-MPI setting -- namely the values from 'argument' will be passed on to the standard input for "mid_wrapper.bf".

Consequently, if you open "mid_wrapper.bf" with

Code:

fscanf (stdin, "String", filePath);
fscanf (stdin, "String", treeString);

 

you should then be able to use filePath and treeString to pass them to 3-rd level files.

HTH,
Sergei
