Thanks for your help, i ran the general tests for the suite on xleap and
sander, both worked with the exception of a rounding problem in sander,
which is not a problem from what i have read in the user guide. i then
tried running the single processor md run but it gave me this:

Rohan 7# mpirun -np 1 ./sander -O -i moldyin -o yayout -p yaytop -c redo
-r retry
MPI: Program ./sander, Rank 0, Process 2057 called

MPI: -----stack traceback ends-----
MPI: MPI_COMM_WORLD rank 0 has terminated without calling MPI_Finalize()
MPI: aborting job

i am just learning the ropes of the program so i apologize if this question is stupid, but do you have any ideas as to what might be going wrong? you said that an input file would help you figure out, so here is the program i am using... it is the program given in the user's guide for a sample with a few numbers rearranged to try and make it work(no success. my professor and i both have tried to figure out what is wrong, but we are out of ideas. program:

moldyin file, first dynamics run
 &cntrl
        imin=0, irest=0, ntx=2,
        ntt=1, temp0=300.0, tautp=0.2,
        ntp=0,
        ntb=1, ntc=2, ntf=2,
        nstlim=500,
        ntwe=100, ntwx=100, ntpr=100,
 &end

i appreciate any help.
thanks,
pmartin
