Systems and methods for processing plant material samples and a transfer station designed for use in such systems and methods. One or more cooling circuits are formed through the platform in order to provide cooling of the platform. The orientation of the drum shaft and shape of the slots cause the vanes to extend and retract relative to the inner drum as fluid pressure or mechanical motion rotate the inner drum relative to the outer drum. According to the method, the composition of the organic material is amended andor inoculated as required to convert the source material to a compostable mixture. The first processor validates the modified keywordURL data to determine if the modified keywordURL data includes errors. The CPU specifies the number of plural layout locations included in the ornamental image data and the priority order of the plural layout locations, and allocates the multiple objective image data to the plural layout locations in the ornamental image data, based on the specified priority order and the ratings of the multiple objective image data.
