Import some example data (as attached here, NOM161121tof.gsa, NOM161122tof.gsa, NOM161123tof.gsa) in Rietveld tab, we then right click on workspaces in Bragg Workspaces tree and all items there in the right click menu will crash ADDIE.

1. For Delete workspace option, we need to go to the definition of function do_delete_gsas in addie/rietveld/braggtree.py. In the for loop there, we are cycling through all workspaces and here, we want to simply skip workspaces. So the old codes are,

   for gsas_node in gsas_node_list:
       # delete the gsas group workspace (deletes sub-workspaces as well)
       gsas_name = str(gsas_node.text())
       gss_ws_name = gsas_name.split('_group')[0]
       self._main_window.get_workflow().delete_workspace(gss_ws_name)

   and new codes will be,

   for gsas_node in gsas_node_list:
       # delete the gsas group workspace (deletes sub-workspaces as well)
       gsas_name = str(gsas_node.text())
       gss_ws_name = gsas_name.split('_group')[0]
       if gss_ws_name == "workspaces":
           continue
       self._main_window.get_workflow().delete_workspace(gss_ws_name)

2. For Remove from plotting option, we need to go to the definition of function remove_gss_from_plot in addie/rietveld/braggtree.py and change the following part of codes,

   if len(gss_wksps) == 0:
       raise RuntimeError(
           'GSAS-single-bank workspace name list is empty!')

   to

   if len(gss_wksps) == 0:
       print("[Warning] GSAS-single-bank workspace name list is empty!")
       return

3. For Merge to GSAS option, we need to go to the definition of function do_merge_to_gss in addie/rietveld/braggtree.py and change the codes from,

   gss_node_list = ret_obj
   if len(gss_node_list) == 0:
       return
   
   elif len(gss_node_list) > 1:
       msg = '[Error] Only 1 GSS node can be selected.'
       msg += 'Current selected nodes are {}.'
       print(msg.format(gss_node_list))
       return

   to

   gss_node_list = ret_obj
   if len(gss_node_list) == 0:
       return
   
   elif len(gss_node_list) > 1:
       msg = '[Error] Only 1 GSS node can be selected.'
       msg += 'Current selected nodes are {}.'
       print(msg.format(gss_node_list))
       return
   
   if str(gss_node_list[0]) == "workspaces":
       print("[Warning] No valid workspace selected!")
       return

4. For To IPython option, we need to go to the definition of function do_copy_to_ipython in addie/rietveld/braggtree.py and change the codes from,

   ws_name = str(current_item.text())
   
   python_cmd = "ws = mtd['%s']" % ws_name

   to

   ws_name = str(current_item.text())
   
   if ws_name == "workspaces":
       print("[Warning] No valid workspace selected.")
       return
   
   python_cmd = "ws = mtd['%s']" % ws_name

5. For Plot option, we need to go to the definition of function do_copy_to_ipython in addie/rietveld/braggtree.py and change the codes from,

   # set to plot
   for gss_group_node in selected_nodes:
       # gss_group_name = str(gss_group_node.text())
       # self._main_window.set_bragg_ws_to_plot(gss_group_name)
       self._main_window.set_bragg_ws_to_plot(gss_group_node)

   to

   # set to plot
   for gss_group_node in selected_nodes:
       gss_group_name = str(gss_group_node)
       if gss_group_name == "workspaces":
           continue
       # self._main_window.set_bragg_ws_to_plot(gss_group_name)
       self._main_window.set_bragg_ws_to_plot(gss_group_node)
