AUTO-MULTIPLE-CHOI(1) Auto Multiple Choice AUTO-MULTIPLE-CHOI(1)
NAME
auto-multiple-choice-note - computes marks after scans data capture for
AMC multiple choice exams.
SYNOPSIS
auto-multiple-choice note --data project-data-dir [--seuil threshold]
[--grain granularity] [--arrondi rounding]
[--notemin min] [--notemax max] [--no-plafond |
--plafond]
DESCRIPTION
The auto-multiple-choice note command computes marks for all students
from the scoring strategy extracted from the LaTeX source file by auto-
multiple-choice-prepare(1) and from the data capture reports made by
auto-multiple-choice-analyse(1).
--data project-data-dir
gives the directory where data files are (see for example auto-
multiple-choice-meptex(1)).
--seuil threshold
gives the black ratio threshold for deciding whether a box is
ticked or not. When deciding whether a box is checked or not,
auto-multiple-choice note compares the black ratio (number of black
pixels over total number of pixels) to threshold. If the black
ratio is greater then threshold, the box is declared to be checked.
Standard values can be 0.15 in the standard layout, or 0.5 for
separate answer sheet layout (in this last case, letters are drawn
in the boxes, and the students are told to fill the boxes
entirely).
--seuil-up upper_threshold
gives the black ratio threshold over which a box is considered as
not being ticked. You can set this value to (for example) 0.6 to
allow students to cancel a ticked box filling it completely: if the
black ratio is between threshold and upper_threshold, the box is
considered as being ticked, but if the black ratio is greater than
upper_threshold (for example when the box is filled), the box is
considered as not being ticked. The default value is 1.0, so that
this feature is disabled.
--grain granularity --arrondi rounding
ask marks to be rounded to a multiple of granularity. If rounding
is 'i', rounding is done from below (as with floor(3)). If rounding
is 'n', rounding is done to the nearest multiple of granularity. If
rounding is 's', rounding is done from above (as with ceil(3)). For
example, with options "--grain 0.25 --arrondi s", mark 6.285 is
rounded to 6.5.
--notemin min
with this option, all marks below min will be replaced by min.
--notemax max
gives the mark to associate to a sheet where all answers are
correct. If not used, marks are not scaled.
--plafond
with this option, all marks above max will be replaced by max.
--debug file.log
gives a file to fill with debugging information.
--postcorrect-student s --postcorrect-copy c
requests port-correction from the completed answer sheet identified
by student and copy numbers. In post-correction mode, correct
answers are not extracted from the LaTeX source file, but taken
from the answers given on this sheet.
