# !! *** same procedure as in TM19_sol, now with polarized ff *** !!

# used TM19 created in moe, then sed chain name in pymol using 
#		alter (all),chain='A'
#		sort 
# then make martini topology: 
# ./martinize.py -f TM19_sed.pdb -o system_vaccum.top -x TM19_pol_CG.pdb -dssp /Applications/DSSP_MAC.EXE -p backbone -ff martini22p

# editconf -f TM19_pol_CG.pdb -o editconf.pdb -bt cubic -d 1 -c

#change martini.itp to #include "martini_v2.2.itp" in system_vaccum.top
# grompp -f minimization_vaccum.mdp -p system_vaccum.top -c editconf.pdb -o minimization_vaccum.tpr -maxwarn 1
