Tutorial on How-to-Rename a great Number of Files at once with a Graphical User Interface (GUI)

Tutorial video on how to rename many files at once using the DocMind Analyst software tool collection

Bulk File Renamer within the DocMind Analyst Software Suite

Providing input files with a certain filename format is a requirement for many analytical pipelines, not just the once offered by the DocMind Analyst. Thus, it is of great importance to be able to rename many files in just a few seconds. The DocMind Analyst provides a section called “Analysis Tools”. Within this section, you will find the “Tool” panel. Here, you can navigate to the “Bulk File Renamer”.

Once started, a new panel will popup. At first, you will be asked for a current working directory. This is a folder that contains the files you want to rename (here the “SPAdes_Assembly” folder). Let’s assume there are two files, one called “ID1_R001.fastq.gz”, the other “ID2_R001.fastq.gz”. They could be sequence reads of two different samples (ID1, ID2), and both would be forward reads (indicated by the R001). Let’s further assume that your analyis pipeline needs these filename in another format. Forward reads should have the format “prefix_1.fastq.gz”. In this case, you would like to change the “_R001” to “_1”. You don’t want to change the unique prefix (here ID1 and ID2). 

Enter in the text field “Text to replace” the part of the file name that you want to replace. Here it is “_R001”. Enter in the text filed “New text” the text that should replace the “_R001”. In this case it would be “_1”. After you have accepted our Terms of Services by checking the respective box, you can start the bulk renamer. All files with a “_R001” in its file name will now have the “_1” at this position. In our example, the two files would be name “ID1_1.fastq.gz” and “ID2_1.fastq.gz”. The prefix has not changed, exactly as we wanted since this is an unique identifier we would like to keep. The advantage of the bulk renamer tool is that you can change the name of thousands of files in just a few seconds – all at once. However, in order to do that, all file names need to have one identical part. In our example it was the “_R001” part of the file name.
