In scientific research, specifically genomics, researchers handle thousands of gene sequences. According to Springer Nature , supplemental files named similarly to "ids.xls" are used to list distinct immune-cell subtypes or Ensembl gene IDs for comparative studies. These files ensure that data remains consistent across different laboratory tools. 3. E-commerce and Inventory
