7 7 2015 Using R to generate expression values and compare replicates from qPCR

Today I needed to find a quick efficient way to compare replicate Ct values using R. I've been working recently at taking raw fluorescence data from my qPCR runs and independently generating efficiencies and Ct values for analysis. The first thing to note is all the data below was generated on the BioRAD CFX programming. To export it properly, I had to remove the baseline subtraction which is default for the BioRad to produce. After exporting it, the rest of the analysis is done in R so as to cleanly compare data. The script below was written specifically to deal with the default CSV export from the BioRAD CFX program. If a different thermocycler/program is used the read in and manipulation of the CSV will most likely have to be changed to accomodate whatever format is exported.

#pcrbatch creates a file with each sample as an individual column in the dataframe. The problem with this is
#that I want to compare all the Ct (labelled sig.cpD2) and generate expression data for them but these values have to be
#in individual columns. To do this I must transpose the data and set the first row as the column names.
act3res<-setNames(data.frame(t(act3ct)),act3ct[,1])
#Now I must remove the first row as it is a duplicate and will cause errors with future analysis
act3res<-act3res[-1,]

#since the sample names are now in the first column the column title is row.names. This makes analys hard based on the ability to call the first column.
#to eliminate this issue, I copied the first column into a new column called "Names"
act3res$Names<-rownames(act3res)

#Since each sample name contains information such as Population, Treatment, and Sample Number I want to separate out these factors
#into new columns so that I can run future analysis based on population, treatment, or both. Also note the "drop = F" this is so the original names column remains.
act3res2<-cSplit_f(act3res, splitCols=c("Names"), sep="_", drop = F)

#After splitting the names column into three new columns I need to rename them appropriately. 
act3res2<-rename(act3res2, c("Names_1"="Pop", "Names_2"="Treat", "Names_3"="Sample"))

#I also create a column with the target gene name. This isn't used in this analysis but will be helpful for future work.
act3res2$Gene<-rep("Actin", length(act3res2))

#In transposing the data frame, the column entries became factors which cannot be used for equations.
#to fix this, I set the entries for sig.eff (efficiency) and sig.cpD2 (Ct value) to numeric. Be aware, without the as.character function the factors will be transformed inappropriately.
act3res2$sig.eff<-as.numeric(as.character(act3res2$sig.eff))
act3res2$sig.cpD2<-as.numeric(as.character(act3res2$sig.cpD2))

#Now I plot the Ct values to see how they align without converting them to expression.
ggplot(act3res2, aes(x=Names,y=sig.cpD2, fill=Pop))+geom_bar(stat="identity")

#Now I want to get expression information from my data set. qpcR has a way of doing this but its complicated and I'm not comfortable using it.
#Luckily there is an equation I can use to do it. The equation is expression = 1/(1+efficiency)^Ctvalue. I tried multiple ways to get this to work in R
#but it doesn't handle the complicated equation easily.
#To work around this, I created a function in R to run the equation and produce an outcome. x = efficiency argument, y=Ctvalue argument
expr<-function(x,y){
  newVar<-(1+x)^y
  1/newVar
}

#Now I run the data through the function and produce a useful expression value
act3res2$expression<-expr(act3res2$sig.eff, act3res2$sig.cpD2)

#Graphing the expression values is a good way to examine the data quickly for errors that might have occurred. 
ggplot(act3res2, aes(x=Names,y=expression, fill=Pop))+geom_bar(stat="identity")

#Before I'm able to compare the replicates I need to process the raw fluorescence from the second Actin run.
#To do this I perform all the same steps as the previous replicate.

act4res<-setNames(data.frame(t(act4ct)),act4ct[,1])

ggplot(act4res2, aes(x=Names,y=sig.cpD2, fill=Pop))+geom_bar(stat="identity")

expr<-function(x,y){
  newVar<-(1+x)^y
  1/newVar
}

act4res2$expression<-expr(act4res2$sig.eff, act4res2$sig.cpD2)

ggplot(act4res2, aes(x=Names,y=expression, fill=Pop))+geom_bar(stat="identity")

#Now that I have Ct values, efficiencies and expression values for both replicates I can create a table of the differences between reps.
#To do this I create a data frame with a single formula that creates a column of values generated by subtracting the first run from the second.
repcomp<-as.data.frame(act3res2$sig.cpD2-act4res2$sig.cpD2)

#Now I need to add some Names for the samples to use with ggplot.Since the names column contains all the relevant information
#I copy only that column and run the split function on it again as well as the rename function. 
repcomp$Names<-act3res2$Names
repcomp<-cSplit_f(repcomp, splitCols=c("Names"), sep="_", drop = F)

#To better address the difference column in ggplot I need to rename it something simple and short. 
repcomp<-rename(repcomp, c("act3res2$sig.cpD2 - act4res2$sig.cpD2"="rep.diff", "Names_1"="Pop", "Names_2"="Treat", "Names_3"="Sample"))

#Now I just run the data through ggplot to generate a bar graph exploring the differences between the two replicate in terms of Ct values.
ggplot(repcomp, aes(x=Names, y=rep.diff, fill=Pop))+geom_bar(stat="identity")

The results are a little discouraging as the replicates show a maximum a 4 Ct difference which is greater than a 10 fold difference in expression values. I'm running another set of replicates today but have slightly changed the protocol again to hopefully optimize it for tight replicate values. 

7 6 2015 Actin 4 qPCR

After noting some significant discrepancies between replicates last week we decided to change the protocol to better help optimize the process and make the data more consistent between runs. Today I'm running two replicates of Actin but this post will only cover the second one. You can read about the other run here. 

Primers:

1505	Ol_Act_F	GACCAGCCAAATCCAGACGA	BC	6/13/2012	20	55	60	O.lurida	Actin, adductor muscle
1504	Ol_Act_R	CGGTCGTACCACTGGTATCG		6/13/2012	20	60	60	O.lurida	Actin, adductor muscle

To help with optimization I made a 1:9 dilution of cDNA so that pipette error would not affect the concentrations as much as it has previously.

Results:

All Samples

NTCs

The samples look good from this run. The appear to both have the same primer dimer issue in the NTCs and the runs look roughly similar. Now I need to compare the two runs with each other to see how closely the Ct's match. I'll post a work up soon on how I did this in R.

NTCs

The samples look good. The NTCs did have amplification but it appears that it was primer dimers and nothing else. I'm running another plate over night and I'll post about it tomorrow as well as how the two replicates match. 

You can see the raw data file here.

July 2015 Goals

These are coming in a few days late due to the holiday. Before I get to what this month's goals are lets look at how I did last month.

June 2015 Goals

1. Run qPCR tests with chosen flanking primers and sequence expression
2. Run qPCR tests with chosen primers to reflect populations level differences
3. Edit Materials/Methods
4. Write Results
5. Have committee meeting 
6. Write Intro/Discussion
7. Get Married!

How I did:

1. I did run most of the flanking primers and sequenced them. Some of the sequencing failed so I had to re run them but I finished that as well. 
2. I ran the qPCR with several chosen primers multiple times. The data hasn't been as solid as we would like so we are attempting to fine tune the qPCR process to get more consistent data. 
3. I failed to really edit Materials/Methods
4. I didn't have any solid results to write up
5. I did however have a committee meeting where we discussed my defense date. It is tentatively set based on if I can produce useful results and write them up this month. 
6. I didn't write an intro or discussion
7. I did get married successfully. 

Overall I see that I got caught up on the lab work aspects of my goals. I was also consumed with figuring out the best way to analyze the data which took up a lot of time but its necessary to be able to write proper results. Overall I need to get my act together this month if I stand a chance of meeting my deadlines for next month. 

July 2015 Goals

1. Finalize analysis script for R to produce expression data and graphs. 
1. Due by 7/9
2. Edit Mat/Meth
1. Due by 7/13
3. Edit Chapter 1
1. Due by 7/15
4. Produce Graphs 
1. Due by 7/17
5. Re-run a host of qPCR with fine tuned protocol to produce consistent data. 
1. Due by 7/20
6. Write Results
1. Due by 7/20
7. Write Intro/Discussion
1. Due by 7/23
8. Complete Thesis Rough Draft
1. Due by 7/29

NTCs

So it looks like there is a deviancy again in 2/4 NTCs. This is distressing as it keeps happening. The previous CRAF run didn't have this issue. It could be possible that I'm contaminating one of the NTCs when I'm pipetting because my hands have been shaking slightly while I pipette. Hopefully I can run this one again without the contamination in the future.
