One query, no joins: ```sql SELECT cancer_study_identifier, name, resource_sample_counts['Slide Microscopy'] AS slide_microscopy_samples FROM cancer_study WHERE resource_sample_counts['Slide Microscopy'] > 0 ORDER BY slide_microscopy_samples DESC; ``` List the resource names that exist with `SELECT DISTINCT arrayJoin(mapKeys(resource_sample_counts)) FROM cancer_study` (e.g. `'Slide Microscopy'`, `'Computed Tomography'`, `'Magnetic Resonance'`, `'H&E Slide'`, `'MxIF Image'`). The map counts sample- and patient-level resources only. For study-level links (`resource_study`) and for the URLs themselves, use the queries below. ## Discovery Query Start with table and column validation, then use this pattern: ```sql SELECT rd.resource_id, rd.display_name, rd.description, rd.resource_type, rs.cancer_study_identifier, rs.url FROM resource_study rs JOIN resource_definition rd ON rs.resource_id = rd.resource_id WHERE lower(rd.display_name) LIKE '%minerva%' OR lower(rd.description) LIKE '%minerva%' OR lower(rd.display_name) LIKE '%image%' OR lower(rd.description) LIKE '%image%' OR lower(rd.display_name) LIKE '%pathology%' OR lower(rd.description) LIKE '%pathology%' OR lower(rd.display_name) LIKE '%histology%' OR lower(rd.description) LIKE '%histology%' ORDER BY rs.cancer_study_identifier, rd.display_name LIMIT 100; ``` If no study-level rows appear, check sample- and patient-level resource links: ```sql SELECT rd.resource_id, rd.display_name, rd.description, rs.cancer_study_identifier, rs.sample_unique_id, rs.url FROM resource_sample rs JOIN resource_definition rd ON rs.resource_id = rd.resource_id WHERE lower(rd.display_name) LIKE '%minerva%' OR lower(rd.description) LIKE '%minerva%' OR lower(rd.display_name) LIKE '%image%' OR lower(rd.description) LIKE '%image%' OR lower(rd.display_name) LIKE '%pathology%' OR lower(rd.description) LIKE '%pathology%' … (981 more chars) ◀ result {"result":[{"cancer_study_identifier":"crc_hta8_htan_2024","name":"Colorectal Cancer (HTAN MSK, Nature 2025)","type_of_cancer_id":"coadread","sample_count":83,"has_guide":false,"url":"https://www.cbioportal.org/study/summary?id=crc_hta8_htan_2024"},{"cancer_study_identifier":"crc_hta11_htan_2021","name":"Pre-cancer Colorectal Polyps (HTAN Vanderbilt, Cell 2021)","type_of_cancer_id":"coadread","sample_count":61,"has_guide":false,"url":"https://www.cbioportal.org/study/summary?id=crc_hta11_htan_2021"},{"cancer_study_identifier":"brca_hta9_htan_2022","name":"Breast Cancer (HTAN, 2022)","type_of_cancer_id":"brca","sample_count":5,"has_guide":false,"url":"https://www.cbioportal.org/study/summary?id=brca_hta9_htan_2022"}]} ▶ list_studies { "search": "OHSU" } ◀ result {"result":[{"cancer_study_identifier":"aml_ohsu_2022","name":"Acute Myeloid Leukemia (OHSU, Cancer Cell 2022)","type_of_cancer_id":"aml","sample_count":942,"has_guide":false,"url":"https://www.cbioportal.org/study/summary?id=aml_ohsu_2022"},{"cancer_study_identifier":"aml_ohsu_2018","name":"Acute Myeloid Leukemia (OHSU, Nature 2018)","type_of_cancer_id":"aml","sample_count":672,"has_guide":false,"url":"https://www.cbioportal.org/study/summary?id=aml_ohsu_2018"}]} ▶ clickhouse_run_select_query { "query": "SELECT cancer_study_identifier, name FROM cancer_study WHERE lower(name) LIKE '%ohsu%' OR lower(cancer_study_identifier) LIKE '%ohsu%'" } ◀ result {"rows":[{"cancer_study_identifier":"aml_ohsu_2018","name":"Acute Myeloid Leukemia (OHSU, Nature 2018)"},{"cancer_study_identifier":"aml_ohsu_2022","name":"Acute Myeloid Leukemia (OHSU, Cancer Cell 2022)"}]} ▶ clickhouse_run_select_query { "query": " SELECT rd.resource_id, rd.display_name, rs.cancer_study_identifier, rs.url FROM resource_study rs JOIN resource_definition rd ON rs.resource_id = rd.resource_id WHERE lower(rd.display_name) LIKE '%minerva%' OR lower(rd.description) LIKE '%minerva%' ORDER BY rs.cancer_study_identifier LIMIT 100 " } ◀ result {"error_message":"Query execution failed: HTTPDriver for https://dl96orhu96.us-east-1.aws.clickhouse.cloud:8443 received ClickHouse error code 47\n Code: 47.

The only HTAN studies present are: - `brca_hta9_htan_2022` — Breast Cancer (HTAN, 2022) - `crc_hta11_htan_2021` — Pre-cancer Colorectal Polyps (HTAN Vanderbilt, Cell 2021) - `crc_hta8_htan_2024` — Colorectal Cancer (HTAN MSK, Nature 2025) - The only OHSU studies present are two unrelated AML cohorts (`aml_ohsu_2018`, `aml_ohsu_2022`), which have no HTAN or imaging resource links. - I also checked `resource_definition`, `resource_study`, and `resource_sample` across all HTAN studies for a Minerva link specifically — none of them have a Minerva viewer resource. The HTAN studies that do have imaging expose "H&E Slide" or "MxIF Image" resources (Vanderbilt CRC and MSK CRC studies), not Minerva. So there is no OHSU HTAN sample with a Minerva viewer link in this cBioPortal instance. This may exist on the separate [HTAN Data Portal](https://data.humantumoratlas.org) or an OHSU-specific viewer outside cBioPortal — could you confirm the study/sample you have in mind, or would you like me to show you the imaging resources that *are* available (e.g., the Vanderbilt or MSK HTAN colorectal studies)?
