Data Descriptions#

Verifying current avaliable location for the dataset now

Samples were extracted using Qiagen’s miRNeasy mini kit (cat. no. 217004) and the RNase free DNase Set (cat. no. 79254), and quantified by Nanodrop and quality was evaluated by Agilent Bioanalyzer.

Batch 1638
Batch 2252 (117 for PolyA selection & 135 for rRNA depletion)
Batch 3251

Notes regarding sample naming: Sequencing samples that were sequenced more than once include the sequencing batch number as the last 2 digits of the id. For example, sample 123_456789_02 is sample “123_456789”, from batch 2. The sample IDs are otherwise randomly-assigned identifiers. Some samples were re-sequenced due to poor quality or low output, they may have “redo” in the sample identifier.
