Calculate the Delta_Ct, Delta_Delta_Ct , Fold Changes and Student's t-tests from qRT-PCR experiment
--Hi,
i have a problem with one of my result using 'pcr' R package, below it's my little input file:
Sample_Name Target Ct
DMSO miR124 29.46
DMSO miR124 29.13
DMSO miR124 29.03
DMSO miR16 24.97
DMSO miR16 24.94
DMSO miR16 25.05
ABX464 miR124 27.1
ABX464 miR124 28.09
ABX464 miR124 26.91
ABX464 miR16 25.09
ABX464 miR16 25.21
ABX464 miR16 25.12
gene control=miR16
condition control=DMSO
Gene of interest: miR124
With 'pcr' package i obtain FC(miR124)=3.98
group gene normalized calibrated relative_expression error lower upper
1 ABX464 miR124 2.226667 -1.993333 3.981559 0.6366579 2.5609434 6.190223
2 DMSO miR124 4.220000 0.000000 1.000000 0.2320919 0.8513995 1.174537
but with your tool i found FC(miR124)=5.11:
python qpcrCalculate.py -d test_interest_data.xls -s Sheet1 -i miR16 -e DMSO -o bioRep

I don't know how to explain this difference, do you have a clue ?
thank you so much.
best,
