EMpty defaults plots in CosmoMc- July 2015 Version
Hi Antony!
I have a little problem when I try to work with the defaults .py.
When I plot the for example the root.pdf or root_3D.pdf from the corrispondent .py I have no problem but when I do the same thing for root_2D I get empty plots while for the triangular plot I get only the marginalization plots along the diagonal, in the rest blank again.
Any suggestion?
Could be a python library-problems or some setting in input files!?
Thank you in advance for the response!
Have a nice day,
The Best,
Alessandro

Can you view them OK in the getdist GUI? Are these scripts from fortran or python getdist?

Hi Antony,
I have produced these scripts by fortran getdist and I think that the problem is connected
with the following: in test_2D_ns_omegach2 file and in other file like test_2D - var1_var2, I get all NaN. Is it right or reasonable?
Thank you!

Not really, do you get the same with the python version? (fortran version is on the way out). If so, assuming there are no NaN in your chain files, perhaps you could send the chain files to try to reproduce it.

Hi Antony,
I have tried to use the python version of getdist on distparam.ini file and I get the following traceback:
chains/test_1.txt

Can this be of some help?
Thank you in advance!

EMpty defaults plots in CosmoMc- July 2015 Version
Hi Antony!
Hi think that I understand the problem related to the empyt bi-dimensional plot.
In distparams.ini file of the last version of CosmoMc there are not the following
command lines:
num_bins = 100
num_bins_2D=40
smooth_scale_2D =2
So I think that without this options, when I interrupt a given simulation I get 2d blanck as results.
I also understand that the traceback (in python getdist) is only a problem concerning which parameters I fix and which not.
Thank you for your help and patience!
