+**Update (02.15.2026):**\\
+The update (asym_memb_builder_v5.tgz) reflects the corresponding modification of ion residue names in IONS, replacing the POT and CAL resnames. In Step 6, phosphorus atoms are constrained in step5_input.ref following CHARMM minimization. Using the helper file (./namd/membrane_lipid_phos_restraint.namd.str), users can modify the constraint settings as needed.
 **Update (08.24.2022):**\\
 The package (v4) was constructed based on bacterial inner membrane models with phospholipids and the system with other lipids should use v5. \\
+The packages may not be able to apply to system with glycolipids.
 The system with proteins should use a limited version asym_memb_builder_v4_prot . \\
-Please provide comments and feedbacks to improve this package. Thanks.

+In step5.2, one should be able to create input for several MD simulation packages by Force Field Converter at CHARMM-GUI page (https://charmm-gui.org/?doc=input/converter.ffconverter)
+where takes the step5_assembly.psf and step5_assembly.crd file generated from step5.1 with step5_assembly.str information.

-In step 2, the two monolayers listing in the input file (**step2_opt_a.str** or **step2_opt_b.str**) are combined to form a bilayer. If there is no adding lipid needed, step2a_gen_bilayer.inp is used with step2_opt_a.str as the input; otherwise, step2b_gen_bilayer.inp is used with step2_opt_b.str as the input. The centers of mass (COM) of both monolayers line on the z-direction. \\
