Opening an RNK File

The RNK file type is primarily associated with GSEA.

RNK	File extension: RNK
	File type:	text file

What is an RNK file?

RNK files mostly belong to GSEA. *RNK files are used to store a ranked list of genes for analysis. They contain gene identifiers paired with ranking metrics that help determine the significance of gene expression differences.
These files are plain text files that you can open with any text editor. However, for proper analysis, software like GSEA is typically used.
Key details as outlined by FilExt.com:

Format: Plain text with gene names and their scores.

Usage: Serves as an input for gene set enrichment analysis.

Functionality: Helps in identifying significant gene patterns.

Access: Can be viewed with basic text editors or processed with specialized bioinformatics tools.

FilExt.com tip: It is important not to alter the file structure as it is vital for accurate data analysis.

How to open an RNK file

You need a suitable software like GSEA to open an RNK file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your RNK file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RNK file directly in the browser:. Just drag the file onto this browser window and drop it.

1. Just click the "Choose your .rnk file to view" button on this page.
2. Your RNK file will then be displayed in the browser.
3. Now click on "Save as..." at the top of the page.
4. Then choose the file format (e.g. JPG, PDF, DOCX, TXT, ...) you want.
5. Your file will be converted and downloaded.

RNK file extension format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the RNK files:

The RNK file extension is rarely used and includes different formats for different programs. The two most common formats are as follows:

• 25% of all RNK files use the same file format, which can be identified by the letters "Gene" at the beginning. The contents of these files can even be read by a human. The files are 45 KB to 370 KB in size, with a median of 370 KB. Certain words are almost always found in the files, such as rank, GeneName, AEBP1, 31.091597469121, 31.533826423921, 31.7641267462069, ANGPTL2, ANTXR1, COL16A1, COL5A1, FBN1 and IGDCC3. The file name Supplementary_Table2_MesenvsImmuno_RNASeq_ranks.rnk is typical for these files. These files can be linked to rnaseq, ranks, supplementary, table, mesenvs, immuno, gsea and ctbp.

The remaining 75% of all RNK files are different files with different signatures. Often described as logfc, mirvsctrl, rank, expression, list, versus, inter or fpkm. You can get all the details of your RNK file by dragging it onto this page or by clicking the button "Choose your .rnk file to view" above.
