Renaming Image Files Automatically

CNALH Barcode Renamer

a program by Daryl Lafferty, Arizona State University

When you use a standardize workflow to digitize specimen, it can be very useful to re-name image files, using catalog numbers as their file name. That way the file name uniquely identified a particular specimen (or its label). This process can be facilitated if your collection uses barcodes as catalog numbers

The Barcode Renamer can read a barcode from an image file and use that barcode to rename the file accordingly.

At Arizona State University we are using this program routinely to digitize Vascular Plant Specimens and upload the files in batch to SEINet.
We are still working on establishing a routine workflow also for digitizing lichen specimens.

The Zip Archiv contains a file called BCR.exe that executes the program. Navigate to the folder, where your image files are located, make to select the correct barcode position and orientation. If you shoot RAW+JPG pairs, make sure to select the checkbox “Rename Raw Files“.

This program works well with full-size herbarium sheets, but includes options to rename images of labels and close-up photos. Please send any bug reports and suggestions to

ASU’s Label Digitization Workflow

Here you can also download an example of ASU’s current Herbarium Digitization Workflow. This document describes in detail how we routinely digitize specimen images of Vascular Plant Herbarium Sheets.
This workflow can be easily modified for the digitization of specimen data of lichen or bryophyte packages. It describes the following steps: (1) capturing digital images of labels, (2) using optical character recognition (OCR) to convert the image files into text, and (3) parsing this text into the database fields using Symbiota’s powerful built-in algorithms [please note: the screenshots in this PDF are using SEINet as an example].
