Dear all Modeller user,

   I follow by so near this question and answers because I have the same error message.

    I do the download of "Updated Windows binary"   and I have the same problem of STACK OVERFLOW.

    I do my example (top scripts) exactly as the example from Modeller basic tutorial avec my data, of course.

    My sequence file is :

>P1;rpb3
sequence:rpb3:::::::0.00: 0.00

     My script file is:

# Example to ALIGN RPB3 with the Template
#
# the template is 1i50C (pdb1i50.ent at C:\Program Files\Modeller7v7\examples\Testes\atom_files)
#
SET OUTPUT_CONTROL = 1 1 1 1 0

# directory with input atom files
SET ATOM_FILES_DIRECTORY = './:../atom_files'

READ_MODEL FILE = 'pdb1i50.ent'

SEQUENCE_TO_ALI ALIGN_CODES = ALIGN_CODES '1i50C', ATOM_FILES=ALIGN_CODES , ADD_SEQUENCE = on

READ_ALIGNMENT FILE = 'rpb3.ali', ALIGN_CODES = ALIGN_CODES 'rpb3'

ALIGN2D

WRITE_ALIGNMENT FILE='rpb3-1i50.ali', ALIGNMENT_FORMAT = 'PIR'
WRITE_ALIGNMENT FILE='rpb3-1i50.pap', ALIGNMENT_FORMAT = 'PAP'

    I find an information at the FAQ messages that there are a Modeller's Variable called "MAXRES". I follow this suggestion from an modeller user: SET MAXRES=5000, and I did not get sucessful!!! but if I uses this ligne above:

        SET MAXRES = 50000000

   I have no 'stack overflow' error message but I have '_E> modeller error message (se the log file above)

   Can you give some help ?

   Many thanks.

This means that Modeller has exceeded the stack space limit. This a constant, set when the Modeller binary was linked, so it won't help if you add more memory to your machine.

Alternatively, you can download just such a 'fixed' binary from the Modeller downloads page: http://salilab.org/modeller/download_installation.html (The link is right at the bottom: "Updated Windows binary".) Use this binary to replace the existing mod7v7.exe file in your Modeller installation (by default it should be in C:\Program Files\modeller7v7\bin), and all should be well.
If these problems persist, let me know.
