title: where do i download gene expression data?
body: <p>i wanted to download gene expression data derived from generated by microarray experiments. i do not know too much about this subject, but as i understand, rows often correspond to genes and columns corresponds to samples. ideally, i expect a matrix of gene expression data. </p>
  
  <p>i've been searching on the internet, and although it may seem like there are many places to download such data, when i actually do download the data, i do not get the matrix of gene expression. could someone please let me know if there is a place or how to download gene expression data in the format that i expect above?</p>
  
  <p>any help is appreciated.</p>
