(a) The Collect tab of the MxCuBE GUI. The sample area in the top portion of the GUI shows information contained in the ISPyB LIMS (sample name, protein acronym, barcode, space group, unit-cell dimensions etc.) for the samples contained in the SC3 sample changer. (b) The sample-changer brick embedded in the Collect tab. The two-dimensional barcodes of the SPINE standard pins contained in the SC3 are read by clicking `scan selected baskets'. The sample currently mounted is flagged in both the sample changer brick and in the sample area (shown in bold green). In this figure MAD/SAD data collection (see text) is not activated.
