Hi everyone, I'm researching growth Differential Expression Genes (DEGs). To do this, I chose fetal , juvenile and adult ages. I found the fetal age data from the GEO site, which was prepared by microarray method and Juvenile and adult ages data from the ArrayExpress site which was prepared by rnaseq method. I calculated the expression values of the microarray and rnaseq data separately. then I agrigate and merge them together based on the gene symbol, next I removed the batch effects. finally I got the differential expression genes. At each stage, the plot was drawn, which showed that the process was correct. Do you think my work process was right? Isn't it a problem that one age is with the microarray data and the other two ages is with the rnaseq data?
