Hi,

I'd appreciate your help with the following. I've been exploring the use of Radiance for sky generation, I've found a problem when using genssky, I get the error:

system: cannot find data file 'Sky/atmos_data/tau_ms_mie_ca_0.12.dat':No such file or directory.

However, the directory and the file exists, but just part of the data is generated (apparently), as is the process was interrupted. The four files in the atmos_data folder are:

irrad_ms_mie_ca_0.12.dat (181 KB); scat_ms_mie_ca_0.12.dat (11,521 KB); scat1m_ms_mie_ca_0.12.dat (11,521 KB); tau_ms_mie_ca_0.12.dat (2,881 KB);

The contents in the files is only one column with thousands of values, and only 3 or 4 values in a second column. I copy the command below:

genssky 6 17 8 -a 53.4666 -o 2.2333 -m -0 -c 1 -n 4 -f June8am -p ./test_hsr

Might this be a problem of memory in the pc? It has 8GB RAM and also sufficient storage space. I'd appreciate any suggestion! Thank you!
