Kragel 270 participant dataset (18 studies x 15 participants) from Kragel et al. 2018 Nature Neuroscience

<br>Note: Individual participant images are <i>not</i> on the same magnitude scale across studies. For most applications, you will want to normalize the scale (e.g., L2 norm or z-score images).<br>This dataset is an fmri_data object class object created using CANlab tools (canlab.github.io). It contains 270 single-participant fMRI contrast maps across 18 studies (with 15 participants per study). Studies are grouped into three domains: Pain, Cognitive Control, and Negative Emotion, with 9 studies each. Each domain includes 3 subdomains, with 3 studies each. <br>The dataset is from Kragel et al. 2018, Nature Neuroscience. Kragel, P. A., Kano, M., Van Oudenhove, L., Ly, H. G., Dupont, P., Rubio, A., Delon-Martin, C., Bonaz, B. L., Manuck, S. B., Gianaros, P. J., Ceko, M., Losin, R. E. A., Woo, C. W., Nichols, T. E., Wager, T. D. (2018). Generalizable representations of pain, cognitive control, and negative emotion in medial frontal cortex. <i>Nature neuroscience</i>. 21(2): 283-289. PMCID: PMC5801068.https://www.nature.com/articles/s41593-017-0051-7it's also stored on Neurovault.org as collection #504. Using CANlab tools , you could get it using:[files_on_disk, url_on_neurovault, mycollection, myimages] = retrieve_neurovault_collection(504);However, this may take a while to download, and you'd have to add metadata for the study category labels to use it. Therefore, we suggest you use the function below. It saves a file on your hard drive the first time you run it:kragel_2018_nat_neurosci_270_subjects_test_images.matThis file also has metadata that is not necessarily on Neurovault. If you save this file somewhere on your Matlab path, you'll be able to reload and reuse the dataset easily.<pre>[test_images, names] = load_image_set('kragel18_alldata', 'noverbose');<br></pre><br>270×6 table<br>Domain Subdomain imagenames Studynumber Orig_Studynumber StudyCodes_______________ ___________ __________________________ ___________ ________________ ____________________<br>{'Pain' } {'Thermal'} {'ThermalPain1' } 1 10 {'Atlas_2010_EXP' }{'Pain' } {'Thermal'} {'ThermalPain1' } 1 10 {'Atlas_2010_EXP' }{'Pain' } {'Thermal'} {'ThermalPain1' } 1 10 {'Atlas_2010_EXP' }{'Pain' } {'Thermal'} {'ThermalPain1' } 1 10 {'Atlas_2010_EXP' }{'Pain' } {'Thermal'} {'ThermalPain1' } 1 10 {'Atlas_2010_EXP' }
