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: the authors confirm that all data underlying the findings are fully available without restriction. the human reference sequence used can be found at the ncbi's anonymous ftp server (ftp://ftp-trace.ncbi.nih.gov/1000genomes/ftp/technical/reference/human_g1k_v37.fasta.gz). the vcf (variant call format) files can be downloaded from the ncbi's anonymous ftp server. it can be either ebi (ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/phase1/analysis_results/integrated_call_sets/) or ncbi (ftp://ftp.ncbi.nih.gov/1000genomes/ftp/phase1/analysis_results/integrated_call_sets/) ftp site. the sequencing reads and sample indexes used in the experiments are available at http://sun.aei.polsl.pl/mugi.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
