Should I use the masked genome or not (chromFaMasked vs. chromFa; both from UCSC) to align my chIP-seq data? If it depends on the alignment programs? Thanks!

I would think this would depend on the aligner you're using, and what you plan to do with multi-match reads.
Depending on what you've precipitated in your ChIP, You're probably more interested in unique regions, anyhow, so I don't think it will make a big difference for the most part. If you were working with whole genome or wtss, I would expect it to have a bigger impact.The more you know, the more you know you don't know. —Aristotle

Definitely unmasked. The repeats masked by repeatmasker (alu, line, sine, mir etc) do contain unque sequences, and probably using masked reference would lead to false alignments of reads from repeats if you allow several mismatches. chr.fa files are also repeatmasked but to lowercase rather than N:s so this information can still be used by some aligners-

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
