To select the data in the specified way, you would first need to access the Illumina 27K and 450K datasets from the Breast Invasive Carcinoma project on the GDC Data Portal [20].
Once you have obtained the datasets, you would need to filter the samples based on the disease types Ductal and Lobular Neoplasms. This can be done by querying the dataset for samples that belong to these specific disease types.
After filtering by disease type, you will be left with a subset of samples that meet the criteria. In this case, you mentioned that a total of 1188 samples were retrieved.
Finally, to visualize the distribution of methylation data from the Illumina platform, you would refer to Table 1 where the distribution of methylation data is presented for the obtained samples.
How do I select data i the followig way?
To verify the proposed approach, Illumina 27K and 450K datasets were obtained from
the Breast Invasive Carcinoma project from GDC Data Portal [20]. The disease types chosen
were Ductal and Lobular Neoplasms. A total of 1188 samples were retrieved. Table 1 shows
the distribution of methylation data from the Illumina platform
