Hi Francesco, 

the output of most files (if not absolutely necessary) is disabled if you run an optimization, in order to reduce the amount of IO.

Cheers

Ok it looks something crashes at the end apparently? But it seems I have the data itself in the files, still not the distribution.

I have version 2.1.0 it seems. I do specify Dist as input, see .tmpl. How would I wait for all the particles to be emitted?

Regards,

Francesco Forcher

Hi Francesco

I believe that should have worked. Which OPAL version and flavour do you use and can you send me your output? You should have a line with Write initial distribution to file "data/<input_filename>.dat" or if there are write problems a line with Unable to open output file.

Also do you specify "Dist" as your input distribution in the RUN command?

Jochem

Hello,

Why  the attribute WRITETOFILE=TRUE for a distribution does not seem to work? I expected to see a file in the data/ directory but nothing has appeared.

This is the command I use (I tried both TRUE and True):





Dist: DISTRIBUTION, TYPE = FLATTOP,
        SIGMAX = 0.00075,
        SIGMAY = 0.00075,
        TRISE = 6.0e-12,      
        TFALL = 6.0e-12,      
        TPULSEFWHM = 20.0e-12,
        CUTOFFLONG = 4.0,
        NBIN = 9,
        EMISSIONSTEPS = 100,
        EMISSIONMODEL = ASTRA,
        EKIN = 0.55,          
        EMITTED = True,       
        WRITETOFILE = TRUE;    //Saves the distribution to a text file

Is there anything wrong?
