Statistical Algorithms Importer: Pre-Installed Project FAQ

F.A.Q. of Statistical Algorithms Importer (SAI), here are common mistakes we have found in Pre-Installed Project.

Windows User

Warning, this type of project will be launched in Linux environment. So be careful, all script files need to have a compatible Linux encoding. For example one difference is that Windows uses \r\n, whereas Linux uses \n for line termination. Another example is that Windows support "Unicode" UTF-16LE, and each character is 2 or 4 bytes, whereas Linux uses UTF-8, and each character is between 1 and 4 bytes. Also be aware of the Cut and Paste operation done from Windows machines that can enter unwanted \r\n characters. To solve this problem you can use the "convert to unix" functionality provided by notepad++ for example, or look for this feature in your editor.

How to use the input and output parameters

For example we consider DiffBasic algorithm:

DiffBasic, SAI

DataMiner show the DiffBasic algorithm in this way:

Bash script code in sample:

echo "DiffBasic Project";
echo "Author: Giancarlo Panchi";
echo "Parameter operator: " $1;
echo "Parameter options: " $2;
echo "Parameter file1: " $3;
echo "Parameter file2: " $4;
echo "Output file: output.txt";
 
OUT="output.txt";
 
case "$1" in
        diff)
            diff $2 $3 $4 > $OUT;
            ;;
 
        sdiff)
            sdiff $2 $3 $4 > $OUT;
            ;;
        *)
            echo $"Usage: $1 {diff|sdiff}";
            exit 1;

How to use Conda Environment

1. !/bin/bash

echo "Ear_Detection"; echo "Parameter: " $1; echo "Output: results.png";

source /home/gcube/conda2/bin/activate eartrack; python -m ear_detection.py $1; source /home/gcube/conda2/bin/deactivate eartrack;
