Comparison of expression values between year and Year2, leaf_postflowering
This document has last been compiled on 2021-12-14 23:38:48.
We ran the same analysis pipeline from preprocessing to differential gene expression (DE) analysis on data when it was mapped to BTx623 (we will call it Year2) and on data when it was mapped to specific genotype, BTx642 or RTx430, (we will call it BT642Year2). In this report, we will analyze the overlap of DE genes identified between Year2 and BT642Year2, focusing on the results from DE spline analysis.
In this file, we compare the raw fpkm counts of samples from leaf and Postflowering between Year2 and RemapYear2.
Below is the analysis of overlap from the raw fpkm counts between Year2 and BT642Year2:

## After filtering: 26 samples 35115 genesMatch BTx623 to OrthologGroup
To compare between Year2 and BT642Year2, we need to match the gene naming. In Year2, genes are named with BT623; and in BT642Year2, genes are names with Ortholog Group. So we implemented mapping the BTx623 gene names to the ortholog groups according to the annotation file.
Mapping BTx623 to OrthologGroup:
## Out of 34211 genes with BT623 names,
## 28538 genes are matched to remap gene names.
## Since 0 out of 34056 remap gene names are mapped to multiple BT623 gene names,
## we collapsed on BT623 with average values of counts so that each remap gene has a unique row.## After mapping the BTx623 gene names to the remap gene names,
## Year2 leaf Postflowering : 51 samples, 34056 genes
## BT642Year2 leaf Postflowering : 26 samples, 35115 genes

Compare gene expressions in Year2 and BT642Year2
In this section, we will compare the log fpkm counts of genes in Year2 and BT642Year2. Particularly, since there are many samples for each gene, we will use the 3rd max log fpkm counts, the average of log fpkm counts in Day063, and the log log fpkm count from a particular sample of each gene to compare.
There are genes that their counts are results from collapsing and we provide comparison of Year2 and BT642Year2 of these genes. Some genes do not have one-to-one relationship of RT430-to-BT642, so their counts were collapsed by summation when we were merging data from two genotypes. They are flaged as Collasped On Ortholog. Some genes do not have one-to-one relationship of BT623-to-OrthologGroup. so their counts were collapsed by averaging when we were mapping BT623 gene names to ortholog groups. They are flaged as Collapsed on BT623. We also provide analysis that focusing on these genes with collapsed values.
