Installing DataCheck

DataCheck is a command line tool that works on both Linux and Windows OSs. It does not require installation and can be used right after downloading the software package. You can decompress it to start using it.

Windows:

Decompress the DataCheck-*.zip package.

The DataCheck-* folder is generated.

You can decompress DataCheck-* to any folder you need.
Go to the DataCheck-* directory.
Find and check the files in the DataCheck directory.

Table 1 describes the obtained folders and files.

Linux

Extract files from the DataCheck-*.zip package.
```
unzip DataCheck-*.zip
```
Go to the DataCheck directory.
```
cd DataCheck-*
```
Check the files in the DataCheck directory.
```
ls 
conf   lib   bin   check_input.xlsx
```
