Thanks, Oliver and Mattia, for you help.
After studying Mattia and Richard's posts, I figured out the following:
Comment out line 15 of TestAbs.arts:
#Copy(abs_xsec_agenda, abs_xsec_agenda__noCIA)
And insert the following to line 16:
AgendaSet( abs_xsec_agenda ){
abs_xsec_per_speciesInit
abs_xsec_per_speciesAddConts
lbl_checkedCalc
abs_xsec_per_speciesAddLines
}
Now it seems working, though I have not yet got the chance to check the outputs
as it is still running.
Yours
Pengwang
