creating parameter file in docker installation

[krishnakumarkkp]

In docker installation, while using command <sudo docker run davidfrantz/force force-parameter /data/force/param LEVEL2 1>, I am getting the following error:

too many non-optional arguments.
Usage: force-parameter [-h] [-v] [-i] [-m] [-c] parameter-file module

Hey @krishnakumarkkp,
in FORCE 3.7.0, the verbosity of parameter files is not given with an suffixed integer but is controlled via the -c flag (see latest documentation for force-parameter). Setting -c creates a compact parameter file, while the default is a verbose one.

[krishnakumarkkp]

But they are optional parameters. I just want to check that what is wrong with the command <sudo docker run davidfrantz/force force-parameter /data/force/param LEVEL2 1> as it is throwing error 'too many non-optional arguments'.

And when I omit the '1' at the end, I am getting an error message: "Unable to open output file!"

Check the usage again:
force-parameter [-h] [-v] [-i] [-m] [-c] parameter-file module
and compare it with your use:
force force-parameter /data/force/param LEVEL2 1

Correct usage: The first argument is the parameter file (output), the second argument is the module (LEVEL2 in your case).
The way you're trying to use it: First argument: module, second argument: verbosity (which is now controlled by the -c parameter, see Florian's response)

Hope that helps

[Florian-Katerndahl]

The command should be: sudo docker run davidfrantz/force force-parameter /data/force/param/l2ps.prm LEVEL2 for a verbose version and sudo docker run davidfrantz/force force-parameter -c /data/force/param/l2ps.prm LEVEL2 for the short parameter file.
The traling 1 should not be included and it is neccessary to specifiy the filename as well.
Edit: The comment this was supposed to answer doesn't show up anymore. Was it deleted?

[krishnakumarkkp]

Yes. I got it. I was supposed to ask the reason for the error message: "Unable to open output file!"' when executing the correct command

ps; Sorry for deleting the previous comment. Came out of misunderstanding

Hi @krishnakumarkkp ,

@Florian-Katerndahl is spot-on.

To elaborate a bit: the usage changed in v. 3.7 to a more Unix-style usage using options. The trailing 1 is now replaced by the -c (compact) option. Also, you now have to specify the output file name, which eliminates the necessity to rename the generated parameter file afterwards (and prevents you from accidentally overwriting previous parameter files when not renaming the files).

I assume that you are referring to some of the tutorials. There is always an indication for the version number for which the tutorial was made. New versions might need some adaptation (as in this case).

Cheers,
David

@krishnakumarkkp,
this is because you have the wrong input data. Please download the data from USGS, untar the package, do not rename anything, do not stack anything
FORCE is meant to work with the original data

[davidfrantz]

or use force-level2, in which case you can even work with the tar archive without unpacking

[krishnakumarkkp]

Yes you are right.
Now with original data from USGS got the following output:

dc: 70.53%. wc: 1.01%. sc: 0.07%. cc: 0.33%. AOD: 0.1169. # of targets: 723/0. 1 product(s) written. dc: 70.53%. wc: 1.01%. sc: 0.07%. cc: 0.33%. AOD: 0.1169. # of targets: 723/0. Number of cols 7855 do not match for UPDATE/MERGE mode (file: 9011). error flushing L2 products.
Flushing images to disc failed! Error in geometric module.

[davidfrantz]

Please delete everything within the output folder (DIR_LEVEL2) and try again.

[krishnakumarkkp]

deleted everything in the 'level2' folder and tried. But again got the same result. Anyway I got something in the level2 output folder. Will check it in detail. But I found nothing in the log and temp folder.

update: Tried with a different image and got the same error. "# of targets: 723/0. Number of cols 7855 do not match for UPDATE/MERGE mode (file: 9011). error flushing L2 products. Flushing images to disc failed! Error in geometric module."

update: I removed the directory 'level2' and created new one using 'mkdir'. Now got the result: dc: 70.53%. wc: 1.01%. sc: 0.07%. cc: 0.33%. AOD: 0.1169. # of targets: 723/0. 1 product(s) written. Success! Processing time: 01 mins 14 secs.

Thanks to all for the wonderful support!
