Duplicates Basics

The Duplicates function removes duplicate lines in a file. The input file can be any tab delimited text file. For example:

Notice that two of the lines occur twice in the file.

Procedure

1. Click Functions. Move the cursor down to highlight File Manipulation and then click on [Duplicates] Remove duplicate lines.
   • 
2. The following window will appear. Click the Browse button and select the file in which you wish to remove the duplicate lines. Click Open and the file name should appear in the box to the left of the Browse button. Then click Submit.
   • 
3. After CNVision finishes removing the duplicates, it will ask if you wish to open the newly created file. Click Yes if you wish to see the new file without any duplicate lines. Otherwise, click No.

Output File

The Duplicates function will create a new file in your working directory named Nodup_Filename.txt where "Filename" is the name of the original file before duplicate line removal.

Notice that every line now occurs only once in the file. All the duplicates have been removed.
