  1. Generate the following files according to STEPS 1-4 from http://xgenes.com/article/article-content/239/small-rna-sequencing-processing-in-the-example-of-smallrna-7/, http://xgenes.com/article/article-content/232/small-rna-sequencing-processing-in-the-example-of-smallrna-7/, and http://xgenes.com/article/article-content/156/small-rna-processing/. For COMPSRA_MERGE_0_miRNA.txt, we also need STEP 5 to add the read numbers of MCPyV-M1.

    COMPSRA_MERGE_0_miRNA.txt *
COMPSRA_MERGE_0_piRNA.txt *
COMPSRA_MERGE_0_snRNA.txt *
COMPSRA_MERGE_0_tRNA.txt
COMPSRA_MERGE_0_snoRNA.txt
COMPSRA_MERGE_0_circRNA.txt

  2. Input files for miRNA are two files: COMPSRA_MERGE_0_miRNA.txt and ids under "/media/jhuang/Elements/Data_Ute/Data_Ute_smallRNA_7/miRNA_WaGa_re"

    • COMPSRA_MERGE_0_miRNA.txt

A little different!! #--> using ./our_out_on_hg38+JN707599_miRNA_merging_replicates/COMPSRA_MERGE_0_miRNA.txt

      cp miRNA_WaGa_on_hg38+JN707599_merging_replicates/COMPSRA_MERGE_0_miRNA.txt miRNA_WaGa_2024 cd miRNA_WaGa_2024

    • prepare the file ids

      #cp ./miRNA_WaGa_on_hg38+JN707599_merging_replicates/ids miRNA_WaGa_2024 for i in EV_vs_parental sT_Dox_vs_sT_DMSO sT_Dox_vs_scr_Dox scr_Dox_vs_scr_DMSO sT_DMSO_vs_scr_DMSO; do echo "cut -d',' -f1-1 ${i}-up.txt > ${i}-up.id"; echo "cut -d',' -f1-1 ${i}-down.txt > ${i}-down.id"; done cat *.id | sort -u > ids #add Gene_Id in the first line, delete the ""
