[--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-dirgives 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.
