If you are using an assembly supported by Partek (e.g. human), there are two radio button options: Download cytoband and Create cytoband from 2bit (Figure 241). Select Download cytoband and click Create to get the cytoband file from the Partek repository. Alternatively, select Create cytoband from 2bit and click Create to build the cytoband file. If the reference sequence is missing, it will either be downloaded automatically or you will be asked to import it from another source (see Adding a reference sequence).

If you are using a custom assembly (e.g. for a non-model organism), only the Create cytoband from 2bit option is available (Figure 2).
