I have attempted to modify the Create Polymer Network protocol to take as input an existing structure and crosslink it only. To do this I have disabled the first pipeline in the existing protocol as follows (first graphic). I have given both xsd and xtd files as the input, but am running into the error (listed below). The create trajectory component was my attempt at making the Cross Linking subprotocol happy with an xsd file as input. How would I go about making this script viable?

Protocol failed: Error executing parallel subprotocol on lynx.a04.aist.go.jp: 'line 1, The expression was trying to access the value of a data record property 'FrameNumber' but it is undefined or could not be calculated. One solution is to edit the PilotScript to test whether the property is defined before using it. This is done with the expression: 0.000000rameNumber' IS DEFINED.'
