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: all data underlying this study has been uploaded to figshare with the following doi: http://dx.doi.org/10.6084/m9.figshare.1392008. the uploaded files include the contents below: 1) a patients 11c-choline pet/ct & 18f-fdg pet/ct image volumes and the ground truth of gtv base on each pet/ct fusion. 2) spss files of t-test, which recorded the process of our data. description of uploaded files: *for convenient data uploading, we converted original dicom images to .hdr and .img image volumes.* 1) ch_ct.hdr & ch_ct.img and ch_intpt.hdr & ch_intpt.img are the pet/ct images using 11c-choline as tracer. ch_t.hdr & ch_t.img are the ground truth of gtv base on the pet/ct fusion. 2) fdg_ct.hdr & fdg_ct.img and fdg_intpt.hdr & fdg_intpt.img are the pet/ct images using 18f-fdg as tracer. fdg_t.hdr & fdg_t.img are the ground truth of gtv base on the pet/ct fusion. 3) t-test.zip file is the spss file recording the process of our data. 3a) doc. vs. doc.sav & doc. vs. doc.spv are associated with table 2, indicating the intra-observer variability. 3b) doc. vs. ref.sav & doc. vs. ref.spv are associated with table 2, indicating the inter-observer variability. 3c) fdg_ref. vs. ch_ref.sav & fdg_ref. vs. ch_ref.spv are associated with table 2, indicating the inter-modality variability. 3d) automethod_fdg vs. ch.sav & automethod_fdg vs. ch.spv are associated with table 3, indicating the inter-modality variability evaluated using auto-methods.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
