Error in sdss_lrgDR7

[gabygga]

am testing the input/sdss_lrgDR7.param file, but I encounter the following error:
Error in Class: spectra_init(L:1297) :error in spectra_pk(pba,ppt,ppm,pnl,psp); =>spectra_pk(L:2793) :error in spectra_sigma(pba,ppm,psp,8./pba->h,0.,&(psp->sigma8)); =>spectra_sigma(L:2884) :error in spectra_pk_at_k_and_z(pba,ppm,psp,k,z,&pk,pk_ic); =>spectra_pk_at_k_and_z(L:688) :error in spectra_pk_at_z(pba, psp, logarithmic, z, spectrum_at_z, spectrum_at_z_ic); =>spectra_pk_at_z(L:418) :error in array_interpolate_spline(psp->ln_tau, psp->ln_tau_size, psp->ln_pk, psp->ddln_pk, psp->ln_k_size, ln_tau, &last_index, output_tot, psp->ln_k_size, psp->error_message); =>array_interpolate_spline(L:1701) : x=9.609418e+00 > x_max=9.609418e+00
I have tried modifying the z_max and k_max values in the .param file, but the error persists.

Any suggestions on resolving this issue would be greatly appreciated!
