You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: In this study, we used the gene expression **data** of Saccharomyces cerevisae or commonly known as yeast from [20]. The original **data** consists of 6,220 gene expression levels taken into 17-time points. The duration of the interval covers two cell cycles of a synchronized sample of yeasts. From the set of monitored genes, 416 of these genes are found to exhibit cell cycle dependent periodicity [3]. The work of Cho et al. [3] also provided a characterization of genes in terms of their involvement in cell cycle regulation. Yeung et al. [25] provided a subset of genes, where no two genes belong to more than one phase. A subset of 384 genes is grouped according to the 5 phases of the cell cycle. Each group corresponds to a specific cell cycle phase which activates in the following order: early G1 phase, late G1 phase, synthesis phase, second growth phase, and mitosis or cell division. In this paper, we refer to the groupings as Group 1 to 5, respectively. We will use the term functional group to refer to the group of genes belonging to a common function. Unless specified otherwise, the main functional grouping of genes is based on the 5 phases of the cell cycle. A more specific grouping was provided in the work of Cho et al. [3], where they provided biological characterization to some of the genes belonging to a single functional group. Examples of such characterizations are genes involved in cell cycle regulation, directional growth, DNA replication, mating pathway, glycolysis/respiration, biosynthesis, and transcription factors.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
