Error: "no lines available in input"

[Aashutosh Aryal]

Hi, 

I am facing the following issue while trying to run the RSWAT:

[SPS-ERROR] 2023-04-30 20:51:34 task 19 failed - "no lines available in input"

The RSWAT runs smoothly but towards the end of the simulation, this error shows up and the simulation run is interrupted. Any help to solve this issue would be great.

Thanks.

[Tam Nguyen]

could you share with me your TxtInOut folder and the RSWATproject.rds file?

[Zsolt Jolankai]

Dear all,

I have received the same message today after a model simulation, can you please share me, what was the solution to this problem? 

Kind regards

Zsolt

[Tam Nguyen]

I checked and in the current RSWAT version, it only work when you selected "Object" and "Conditions" are "All". I need to check SWAT+ if they updated SWAT+ or there is something wrong with RSWAT

[Tam Nguyen]

I have updated RSWAT

Now you can calibrate for any "object" and "condition".

@ Zsolt 

The error " [SPS-ERROR] 2023-04-30 20:51:34 task 19 failed - "no lines available in input"" 

because you didn't tell SWAT+ to print out the output file (should put "y" in lines 42 of the print.prt file) and  put "calibration.cal" in lines 22 of the file file.cio instead of "null"

Dear Tam,

thanks you very much, the simulation runs now without error.

best regards

Zsolt

Dear Jolankai,

I am kind of facing the same challenge, however, I have tried to follow instructions you were given but it's not working for me. Would you mind to assist me. Please see the attache errors I am receiving once I click run SWAT.

I have attached file.cio as well.

Regards

Sydney.

[Zsolt Jolankai]

Dear Sydney,

I think you should not put calibration.cal at each column in your change line (chg). The values you can use here are described in the manual: cal_params.cal should be the first and calibration.cal should be the second item.

With regard the message: I am experiencing the same problem again, even if my text files are correct (I believe).

Error: [SPS-ERROR] 2024-05-10 12:43:22.303578 task 1 failed - "no lines available in input"

Dera @Tam, can you please check the problem for my case? 

Best Regards

Zsolt

[Tam Nguyen]

could you just run SWAT+ independently (click to the SWAT+ executable files in the TxtInOut folder) to see if it work

Did you solve this error? I am getting the same message.

I think the problem is from the range that has been set for each parameter at Step2. 
When using parallel processing, you would notice some core(s) run till the end but others do not. Those that stop are those where at least one parameter value sampled is out of bound. To solve the problem, open your wolkingFolder/output then "CurrentSimulationReport.log". From there you can determine the core(s) that could not achieve it's simulation. Open the TxtInOut_x corresponding, then calibration.cal, there you will see the values sampled for each parameter. You can use your experience to determine the parameter(s) and the value(s) out of bound or start deleting parameters (the whole line) one at a time and running  the model using the executable which is already in the TxtInOut_x folder. It will keep failling until the parameter(s) out of bound is (are) removed. Once the parameter(s) out of bound is determined adjust the value until SWAT (executable) could run properly. Reajust the range then and restart the process at Step2. The parameter out of bound in my case was bd.sol

I hope this would help, good luck.

Dear Tam,

I have the error " task 1 failed - "no lines available in input",

I have made adjustments to my file.cio and print.prt files as suggested by comments here, but i still have the same error.

I would appreciate your help please.

Hi all,

Alfa's suggestion to identify what the problem is is very useful! First, identify the problematic core and in the TxtInOut_x folder you can run your debug executable using cmd or powershell. This will tell you which parameter is out of bund.

It is very important to have in mind that objects to apply the parameter sampling are not "name id" but the "unit id". For instance, I was using aqu100, but the unit id (which you can find in the .txt of each element as "unit" column) was 10.

I hope this helps,

[Tam Nguyen]

Hi Faven,

Thank your for this remark. I think this remark should be added to the RSWAT help button (but it needs further verifcation).

could you share with me your TxtInOut and a more detail description to demonstrate your point " It is very important to have in mind that objects to apply the parameter sampling are not "name id" but the "unit id". For instance, I was using aqu100, but the unit id (which you can find in the .txt of each element as "unit" column) was 10."

This could help other when using RSWAT
