At first, you have to get the analysis result file of CCFinder.
Following is the process.

You will find "get token-based code clone" label in the following screen.
Push its next button.

After pushing the button, following screen appears
If you have a list file that includes target files, push the "Load List" button.
If you don't have, you have to specify target files, push the "Select File or Directory" button.
After pushing these button, file selection dialog box appears.
You can select a file or directory.

As following screen, if target files are listed, push next button.

Here, you can specify options of code clone detection.

Following options are available.

Minimum Clone Length

This is the minimum token length that CCFinder detects(mandatory)

Memory Resource Limit

CCFinder devides source files according to this option(mandatory).

Language Select

This is the language of target files

Detection Option

This option decide what kind of code clones will be detected.(mandatory)

Analysis Result File...

This is the file path which Aries writes analysis result to.(mandatory)

Other Options ...

Here, you can specify other options that CCFinder has.

After specifying options, push the "Run CCFinder" button.
Then, after outputing log of detection, "Successfully Finished" appears.
Using this process, you can get the analysis result file of Aries.
In next phase, you analysis clone sets using Gemini.
Push OK button of "Successfully Finished" dialog box, and return initial screen.

Memory Resource Limit

This is the maximum memory size that Java VM uses(mandatory)

Analysis Result File...

This is the file path(the analysis result file of CCFinder) that you got above.(mandatory)

Other Options

This is other options(optional)

RAD(S)

RAD(S) represents the range of the source code fragments of a code clone in the directory hierarchy,
when the source code is supposed to be stored in the hierarchical directory.
When all the code fragments of a clone class are located in one source file,
the RAD(S) value of the clone class is equivalent to 0.
When the code fragments of the clone class are located in multiple source files stored in one directory, the RAD(S) is 1.
If those sources files are stored in different directories,
then RAD(S) is the maximum depth of those sources measured from their common parent directory.

LEN(S)

LEN(S) means the average of token number that clone set S includes.

RNR(S)

RNR(S) reprensents the ratio how clone set S consists of non-repeated token sequenses.

For example, repeated token code clone is continous printf.
Most of these clones are rarely meaningful from our experiments.
Using RNR(S), we can filter such code clones.

POP

POP(S) means the number of code fragments which are included in clone set S.

DFL

DFL(S) indicates how many tokens would be removed from source codes if all code fragments are merged.

NOL

This is the line number of the file.

NOT

This is the token number of the file.
Tokens in commends are not counted.

NOC

This is the clone number which are included in the file

ROC

This is the ratio how fhe file is cloned.

NOF

This is the number of files that share code clones with the file.

Location

This is the location of the code clone.
The format is "StartLine.StartColumn - EndLine.EndColumn".

Length

This is the token number of the code clone.

Dispersivity

This means how the code clones are distributed in file system.
If all code clone are in a same file, "dense" is displayed.
If all code clone are in a same directory, "middle" is displayed.
In other cases, "scattered" is displayed.
Also, the highlight color is different by the degree of distribution.
"dense" is red.
"middle" is green.
"scattered" is blue.

Equivalence

This is the number of code fragment that is cloned with the code clone.

NOL

This is the line number of the file

NOT

This is the token number of the file

Tokens in comment are not counted.

NOC(f)

This is the clone number that the file shares with file f.

ROC(f)

This is the ratio how the file is cloned with file f.
