SumDiagrams[nKernels,name]

Sum the result of TraceDiagrams from the directory "TraceBuffer/name" into a file "TraceBuffer/sum.m" and return the expression.

SumDiagrams[nKernels,name,number]

Subdivide the result into several sub-expressions. If 0 is given, the diagrams are normally resummed into a single expression.

SumDiagrams[nKernels,name,number,operation]

Apply the operation to all diagrams before summing. The standard operation is to use $StandardQuickSimplify.

SumDiagrams[nKernels,name,number,operation,outputName]

Save the diagram to outputName instead of the standard "sum.m".
