Differential Expression on Flux capacitor output

Dear Team,

For Differential expression, we are using tweeDEseq method which will take read counts as input and noramlize counts using TMM method and perform pair wise comparisons.
As RPKM values already already normalized counts, can I consider "reads" section from flux-capacitor results as input to tweeDEseq?

here is the few lines of output from flux-capacitor

18 ENSEMBL transcript 158483 213739 . + . transcript_id "ENST00000261601.5"; locus_id "18:158483-213739W"; gene_id "ENSG00000101557.8"; reads 4644.136719; length 4156; RPKM 2497.995850

Please let me know your suggestions.

Thanks in Advance
