Understanding MAF Issues


Issues Opening MAF Files

Microsoft Notepad is Not Installed

If you attempt to load your MAF file, you experience a message such as "Can't Open MAF Files". If this is the case, it's usually due to the fact that you do not have Microsoft Notepad for %%os%% installed on your computer. The OS won't know what to do with your MAF file, so double-clicking to load the file doesn't work.


Tip: Another MAF-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Wrong Version of Microsoft Notepad is Installed

Occasionally, you might have an outdated version of Microsoft Notepad installed that's incompatible with your Mutation Annotation Format File type. Download the latest Microsoft Notepad version from the Microsoft Corporation website to ensure you have the correct one installed. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: You can sometimes get hints about the right program version by right-clicking on the MAF file, selecting "Properties", and looking at the version information.


Regardless, most of the MAF file opening problems relate to not having the right version of Microsoft Notepad installed.


More Causes of Problems Opening MAFs

Although you might already have Microsoft Notepad or another MAF-associated software installed on your computer, you can still encounter problems opening Mutation Annotation Format File files. If you're still experiencing problems opening MAF files, there could be other computer problems. Other contributing causes:

  • Windows Registry MAF file paths that are incorrect
  • Unintentional removal of the description of the MAF file inside the Windows Registry
  • Microsoft Notepad or another MAF application experienced a flawed installation
  • Your MAF can't be loaded properly (file corruption)
  • Your MAF has adversely impacted by malware
  • Hardware associated with MAF has outdated drivers
  • Your PC doesn’t have enough available resources to open the Mutation Annotation Format File file
