I used TLS parameters and NCS restraints. WXC_scale and WXU_scale are 0.50 and 1.0 respectively. Rwork and Rfree are 18.09 and 19.62 respectively. I tried with reducing WXC_scale and WXU scale to 0.25 and 0.30 respectively but it did not help. Please suggest me if I need to change some parameters. I shall be grateful for your help.
