Input file formats
On this epigraph the two different input file formats supported will be described.
Restrictions: Only integer scores are supported
File format: Each line contains the number of scores equals to the index of the line in the file (starting from zero). For example, given a file:
The above file example indicates that there are 123 scores equals to 0, 12 scores equals to 1, 212 scores equals to 2, 321 scores equals to 3 and so on.
Recommendations: Use this format for very large experiments.
Note: Only impostor scores file can mimic this format.
Restrictions: None. Integer and float scores are both supported.
File format: All the scores one by line
console cmd: geteerinf
To print the script help
python geteerinf -h
One experiment (Non-histogram format):
python geteerinf -p "example_files/non_hist/" -i "exp1_false" -g "exp1_true" -e "exp1"
More than one experiment (Non-histogram format):
python geteerinf -p "example_files/non_hist/" -i "exp1_false,exp2_false" -g "exp1_true,exp2_true" -e "exp1,exp2"
One experiment (Histogram format):
python geteerinf -p "example_files/hist/" -i "exp1_false" -g "exp1_true" -e "exp1" -ht
Note: To run the above examples you can download the example files from the project site on Gitlab or extract them from inside the package installation
