 Be sure to specify a version greater than version `v1.0.0` - prior to this version the `cellfinder` package had a very different structure that is incompatible with BrainGlobe version 1 and the other tools in the BrainGlobe suite.
 See [our blog posts](https://brainglobe.info/blog/) for more information on the release of BrainGlobe version 1.
