Correction Author: David A. Pearlman
Correction Date: 06/13/94

Programs: Sander

Severity: slight

Problem: 

       Although the documentation describes the availability of the
       option NTT <= -2, an attempt to set NTT<-2 would result in
       SANDER stopping with the error message

           NTT (ntt_value) must be in -2..5.

Affects: 

       Program would terminate immediately with NTT<-2.

Cause: 

       An inappropriate bounds check on the value of NTT was being
       performed.

Fix:  Make the following changes to routine MDREAD in sander

---Sander: Module mdread.f  -----------------------------

*** OLD mdread.f
--- NEW mdread.f
***************
*** 575,582 ****
          write(6,'(/2x,a,i3,a)') 'NRUN (',nrun,') must be >= 0.'
          inerr = 1
        endif
!       if (ntt.lt.-2 .or. ntt.gt.5) then
!         write(6,'(/2x,a,i3,a)') 'NTT (',ntt,') must be in -2..5.'
          inerr = 1
        endif
  c
--- 576,583 ----

          inerr = 1

!       if (ntt.gt.5) then
