| dc.description.abstract | For STAR-experiment associated research at Brookhaven National Laboratory, the primary objective is the study and characterization of the Quark-Gluon Plasma, or QGP. The data is stored in subsets of the original, full 'Data Summary Tape' or DST format. The PicoDST format is the new, more compact way in which all data from particle collider experiments is stored. Because this data format is relatively new, much of the existing data analysis scripts written by the TAMU group to run on root4star (the modified ROOT software package used for the STAR experiment) work only with MuDST-type files, which is the older format. While extensive documentation exists for both the PicoDST and MuDST formats, not every aspect is exactly analogous, and therefore methods to convert older MuDST-scripts to perform the same analytical functions with PicoDST files must be created. In this paper, the differences between the PicoDST and MuDST formats will be considered, as well as the differences between algorithms written to accomplish the same task with either format. In addition, a significantly higher time-efficiency is demonstrated for a particular PicoDST algorithm when measured against its MuDST counterpart. | |
