Hi all,

I am accessing the assembly data to calculate the fold change.

The command I had used:

> transcript_fpkm=texpr(bg_filt, 'FPKM')
> write.csv(transcript_fpkm, file="B1transcript.csv")

> head(transcript_fpkm)
   FPKM.B1C_01 FPKM.B1T_01
5     3.073159    1.206581
18    0.000000    2.401758
21    0.000000    9.711361
22    4.447027    1.147893
25    0.014155    4.940222
27    4.032991    0.258391

Please advise me on what the first column values indicates. Also, are these FPKM values calculated by Stringtie and Ballgown tools logged or unlogged?

Thanks
