CosmoMC 2013 run

[Vanessa Smer]

Dear Antony

After successfully compiling CosmoMC June 2013, I am trying to run it. However, after doing:

./cosmomc params.ini

I get the following:

I used:

grep -r -n forrtl

But didn't help. It seems like "forrtl" should be a file but is a directory? Do you know why this happens?

Thanks!

Hi Vanessa,

forrtl actually stands for Fortran Run Time Library. "forrtl: ...." pops up and indicates there was an error running the program.

forrtl: severe (39) indicates that there was an error while trying to read a file. In this case some file path was pointing to the current directory rather than the file cosmomc was trying to read.

Based upon when you received the error, it looks like there is an issue with the file path to the covariance matrix defined in params.ini with the line:

Code: Select all

propose_matrix =

Hope that helps.
