Thank you for repling and explaining.

When we tried to run in the cluster, there is no kfile created and the error jumped out several similar lines as following:

(process:103941): Gdk-CRITICAL **: 00:12:55.741: IA__gdk_screen_get_width: assertion 'GDK_IS_SCREEN (screen)' failed
(process:103941): GLib-GObject-WARNING **: 00:12:55.745: invalid (NULL) pointer instance
(process:103941): GLib-GObject-CRITICAL **: 00:12:55.745: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

However, we just tried to run in LSPP GUI in the local computer, and found it successfully created the part.

We need to run lsopt in the cluster, so creating parts also needs to be done in the cluster. Is this issue caused by the the command in run file or is anywhere in cfile should be editted for running in the cluster? The following figure is our command in runfile.
