Process

  1. Filter reads using Schizont transcriptional profile.
  2. Align to reference sequences (using HISAT2).
  3. Remove human reads from alignment (using Samtools).
  4. Map remaining reads to P. vivax genome (using Rsubread) and count gene frequencies.
  5. Perform deconvolution of the samples (using CIBERSORTx).
  6. Compare the 43 transcript expressions (using DESeq2 or edgeR)...
    • relative to Saimiri (Duffy-negative) and Aotus monkey P. vivax from Gunalan et al. (2019) paper.
    • relative to the 26 Cambodian P. vivax from Kim et al. (2019) paper.
