auto-multiple-choice-note — computes marks after scans data capture for AMC multiple choice exams.
auto-multiple-choice note --data
project-data-dir [--seuil threshold] [--grain granularity] [--arrondi rounding] [--notemin min] [--notemax max] [ --no-plafond | --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-dirgives the directory where data files are (see for example auto-multiple-choice-meptex(1)).
--seuil
thresholdgives 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_thresholdgives 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 roundingask 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
minwith this option, all marks below
min will be replaced by
min.
--notemax
maxgives the mark to associate to a sheet where all answers are correct. If not used, marks are not scaled.
--plafondwith this option, all marks above
max will be replaced by
max.
--debug
file.loggives a file to fill with debugging information.
--postcorrect-student s
--postcorrect-copy crequests 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.
