- Set up user page on OpenWetware
- Saved Schade data and pdf file to flash drive
Schade Data Organized
- Column A has the systematic of all the genes.
Note: The next columns will be presented in groups of three for an specific chip. The columns are broken down into normalized, raw, and control data (in that order).
- Columns B,C,D belong to the 257659.txt chip at time(t)=0.
- Columns E,F,G correspond to the 257720.txt chip at t=0.
- Columns H,I,J belong to the 258333.txt chip at t=0.
- Columns K,L,M belong to the 12164589.txt chip at t=10minutes.
- Columns N,O,P correspond to 12164610.txt chip at t=10minutes.
- Columns Q,R,S belong to the 12164813.txt chip at t=10min.
- Columns T,U,V belong to the 12251647.txt chip at t=10min.
- Columns W,X,Y belong to the 12251674a.txt chip at t=10min.
- Columns Z,AA,AB belong to the 12251693.txt chip at t=10min.
- Columns AC,AD,AE belong to the 12251985a.txt chip at t=10min.
- Columns AF,AG,AH correspond to the 257384.txt chip at t=30min.
- Columns AI,AJ,AK belong to the 257657.txt chip at t=30min.
- Columns AL,AM,AN belong to the 257661.txt chip at t=30min.
- Columns AO,AP,AQ belong to the 257662.txt chip at t=30min.
- Columns AR,AS,AT belong to the 258277.txt chip at t=30min.
- Columns AU,AV,AW belong to the 258317.txt chip at t=30min.
- Columns AX,AY,AZ correspond to the 275072.txt chip at t=2hr.
- Columns BA,BB,BC belong to the 275130.txt chip at t=2hr.
- Columns BD,BE,BF belong to the 275146.txt chip at t=2hrs.
- Columns BG,BH,BI belong to the 275151.txt chip at t=2hrs.
- Columns BJ,BK,BL belong to the 12251635.txt chip at t=12hrs.
- Columns BM,BN,BO correspond to the 12251649.txt chip at t=12hrs.
- Columns BP,BQ,BR belong to the 12251956.txt chip at t=12hrs.
- Columns BS,BT,BU belong to the 12251987.txt chip at t=12hrs.
- Columns BV,BW,BX belong to the 185234 .txt chip at t=60hrs.

- Column CN is the standard name of the gene.
How to use MatLab
- To use MatLab we will need a know where locate our documents. The data will be found under computer in the Local disk C.
- Once we are in the disk, we will choose the folder gene_regulatory_modeling where we will find the excel data needed and MatLab programs written.
-When making changes to the excel data we must make sure that degradation rates, production rates, and parameters are all correct. -ex. If we were to be analyzing three genes we must have three production and regulation rates. Also, when we look at the network and see how many 1's appear, that will be the number of weights and thresholds that will be in our parameter. (Note. The 1's must be read from left to write until the row ends, and then we can move on to the next row.)
- Once we have chosen which excel sheet we need, we will open it
- From there we will open the MatLab program that contains the differential equation program that we need for the particular experiment(we must open MatLab first and the locate our document).
- From there we just have to press the run button (once changes have been made and saved) and analyze the graphs given.
- After we run the program, there will be an output file that will let us know the Log 2 concentrations.
- We came into the lab and created a new worksheet in excel to place only the normalized data so it could be analyzed. We copied and paste the Schade data into the new worksheet. The numbers in the data represent the ratio between red and green spots in the microarrays.
- In the new worksheet we transferred and the data and organized it in a way that we would understand it.
1. We renamed each chip. Their name is, t for time, the time it was looked at and the sample number. (An example would look like t0-1 meaning, it is the first sample for time at t=0). 2. We deleted the raw and control columns leaving only the normalized.
- When looking at the data we noticed that the number of samples for each time were different. For time at 10 minutes there is an extra sample. Also, we do not know which samples are paired with each when they were dye swapped.
