Dear All,
I took a protein-RNA complex for MD studies. Then I separated protein and
RNA since the purpose the the study is to compute the affinity between
protein and RNA. Further I ran tleap using the script to combine the
protein (File named as "rec1.pdb" in attachment) and RNA (File named as
"rec2.pdb" in attachment) in AMBER12. After running the tleap script (File
named as "tleap.all" in attachment), the followoing error was observed.
Can you please help me to fix these errors
