YOUR HELP WAS GREAT FOR ME !

I have revised the input files and deleted the misprints.

( ~ 10 atoms) : the "gradient out of range" error disappeared and the job terminated successfully.

( ~ 200 atoms) :  the "linear dependence" error disappeared in the check run and the main job is running now and I hope I never see the error.

Attached please find the main and check files.

I profusely apologize for the typos and misprints which waste the time of you and this good discussion club. I do wish the best for you in the new year.    

Sincerely Yours
David
