I encountered some errors while using CAMB to calculate the primordial bispectrum. I'd be really grateful if someone could help me.

To calculate the primordial bispectrum, I started by modifying the default params.ini on the following four lines:

do_primordial_bispectrum = T

bispectrum_slice_base_L = 2

bispectrum_full_output_file=bispectrum

bispectrum_full_output_sparse=T

But CAMB comes back with:

Code: Select all

```
