h5. Analysis of batch vs clinical traits

Number of clinical traits: 23

Number of batches based on the pattern for DNA methylation samples: 3

Correlation between batch and center in AML:
{code}> table(batchID,two)
       two
batchID AB
   0741 96
   0742 73
   0743 25{code}
There is only one center from which all patients come from. 
Significant trait - batch correlations (all other correlations can be found in a table [here|^BatchClinicalInfoCorrelationsLAML.csv])
