--plafond]
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
--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.
