SUEWS ANALYSER ERROR

[phemiobe]

Hello, In visualising the spatial model output using the SUEWS analyser, the error pasted below comes up. the python programme is searching for a particular file which I dont have. I have 336 grid points and 336 output files. the program is searching for Suews_output2000//337_2000_SUEWS_60.txt. when my last output file is Suews_output2000//336_2000_SUEWS_60.txt. I even tried to copy and rename the sile 336 as 337; it the searches for another missing file 338...

Kindly help. I am however able to plot the time series and scatter plots of variables

The ID from the vector grid is used as counter here. Make sure that you use the same grid as you used to prepare your input files. How many grids does your polygon layer consistof?

[phemiobe]

I have always used thesame grid as used in the input files. My polygon Layer consist of 336 grid points.

[biglimp]

And your ID attribute starts from 1?

[phemiobe]

yes, starts from 1 to 336

[biglimp]

Ok, can you attach the input files, output files and your vector grid in a zipped file for me to have a look at.

[phemiobe]

Unfortunately, I find it difficult to attach zip file here. I however rerun the model and I got this error when I tried to visualise the output

This is progress. Now the code has come to a point where all grids have been analysed without error. I think your new error is related to a bug in the path to the vector grid. I have pushed an update so try to install the development release and see if it works. Alternatively, you can try out the SUEWS Analyser in UMEP for processing instead.
