RSWAT SUFI-2 error: 'no lines available in input' (print.prt checked)

[Mahabub Chowdhury]

I am currently running SWAT+ with RSWAT (SUFI-2) without the GUI and encountering a persistent issue.

The SWAT+ simulations complete successfully, but during RSWAT post-processing I repeatedly get:

Error in { : task X failed - "no lines available in input"

I have verified that:

• print.prt has all outputs set to y, including channel_sd with daily output
• channel_sd exists in the TxtInOut folder
• time.sim is properly defined (daily step, correct simulation years)
• channel_sd_day.txt is generated, but some simulations contain only headers (no numeric rows)
• When the model does run, all extracted output variables (e.g., flo_out) are zero (in the working folder -inside the core-x)

Even after detecting and re-running those failed simulations, the error still occurs intermittently.

Is there a recommended way to skip failed simulations?

Thank you very much for your time and help.

Best regards,
Mahabub
