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

Text: the authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. bam files are available from the cancer genome atlas via the ucsc cancer genomics hub https://cghub.ucsc.edu/. variant call format (vcf) and mutation annotation format (maf) files are available from the tcga data access portal at https://tcga-data.nci.nih.gov/tcga/. open-access somatic mafs can be visualized and downloaded via the ucsc cancer browser (https://genome-cancer.ucsc.edu/) [55]. tcga barcodes and universally unique identifiers (uuids) for the tcga samples used in this study can be found in table s2. software available at https://github.com/aradenbaugh/radia/.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
