The following DNA-seq BS IDs should be added to patients, since they are the only DNA-seq samples available:

PT_YCMH9SQP: BS_A70G7S2W PT_EV71W1JW: BS_YETTZ1NC

Quick question, why specifically only those two samples? It seems there are total 11 participants that only have Metastatic samples (4 Targeted Sequencing and 7 WGS samples):

# Filter to only DNA samples from tumors, where composition is not "Derived Cell Line" and "PDX", and are not metastatic
tumor_samples <- histology_df %>%
  dplyr::filter(sample_type == "Tumor",
                !composition %in% c("Derived Cell Line", "PDX"),
                is.na(RNA_library),
                experimental_strategy %in% c("WGS", "WXS", "Targeted Sequencing"),
                !grepl("Metastatic secondary tumors", pathology_diagnosis, ignore.case = FALSE, perl = FALSE,
                       fixed = FALSE, useBytes = FALSE))

# Filter to participants with only Metastatic samples 
tumor_samples_only_met <- histology_df %>%
  dplyr::filter(sample_type == "Tumor", 
                !composition %in% c("Derived Cell Line", "PDX"), 
                is.na(RNA_library), 
                experimental_strategy %in% c("WGS", "WXS", "Targeted Sequencing"),
                grepl("Metastatic secondary tumors", pathology_diagnosis, ignore.case = FALSE, perl = FALSE,
                       fixed = FALSE, useBytes = FALSE))
tumor_samples_only_met <- tumor_samples_only_met %>%
  filter(!Kids_First_Participant_ID %in% tumor_samples$Kids_First_Participant_ID)

@komalsrathi I think only those two samples were included in a germline cohort we are working with, so I didn't realize there were others that are falling into the same category.

[komalsrathi]

Oh okay, then I think it is acceptable to include the 11 samples listed above? If you agree with it then I'll create a PR with the changes.

Hey @komalsrathi - @rjcorb and I were chatting about this since we did not realize these were mets. I would like Jenn to look into these before we add - I am not sure if it makes sense to add these if they may not have initial tumors in the brain. Eg some are osteo, nbl - so I want to hear back from her about the initial diagnoses first. I guess if they are initial solid tumors, we possibly can shift them out of PBTA cohort and into the appropriate cohorts or figure out some other way to handle, while making sure they are still in the independent specimen list. So let's just pause on this one.

[komalsrathi]

Ok sure, I did rerun and push the results to a new branch but I will hold off on creating a PR.
