The first 3 scripts run very fast, but but it took a very long time for the "run_irfret.sh". In fact, I started it the script 2 hours ago, and it still stays at "adjusting and getting IRFs - scond round". Is it normal?Thanks,Below is the scirpts I ran. 1 run_pestica_ica.sh2 run_pestica_est.sh3 filter_pestica_est.sh4 run_irfret.sh
