Error in correct confluences

[mvalbuena09]

Hi.
I have tried to execute the workflow with the example data that is contained in the documentation, but I have had an issue in relation with the correction of the confluences. The issue says that the streams, generated by the command derive_streams has a longitud which value is 0.

if (cp)

• correct_compl_confluences()
  Fixing 107 complex confluences with 3 upstream segments each
  Original stream topology file moved to 'streams_v_o3'.
  Breaking lines and moving vertices ...
  Updating topology ...
  Error in if (dt.move_streams[jj, cut_stream_prev] != i) { :
  argumento tiene longitud cero

What could be a solution for this issue?
I tried to generated a stream in ArcGIS and import it as an input of correct confluences, but a message appeared telling me that was necessary to calculate the streams netowork throught the Open Stars Workflow.

Thank you for your help.

Best Regards,

Martha.
