Description Usage Arguments Details Examples
This function is for calculating GC content in CRISPR/Cas9 deletions that have already been analysed using the mhq function. It filters the deletions for those with a given amount of microhomology and then performs a chi sqaure test to compare the observed vs the expected GC content of the microhomologies.
1 | gcq(input, MH, equalTo = F, expected, CRISPResso = T)
|
input |
dataframe output after running mhq(yourData) |
MH |
microhomology amount to filter for |
equalTo |
if set to TRUE search ONLY for microhomologies equal to MH. If set to FALSE search for microhomologies greater than or equal to MH |
expected |
background GC content over the region containing deletions (if 50 percent background, expected=0.5.) Determined by the user. |
CRISPResso |
are you analysing a dataframe containing analysed CRISPResso data? |
Output is a dataframe with columns:
baseType = GC bases or AT bases
baseNum = number of bases of each type (in alleles with the given amount of microhomology)
baseProb = observed number of bases of each type in the microhomologies analysed (0 to 1 a.k.a 0 to 100
expectedProb = expected probability (0 to 1) of bases of each type (known background for the region of the deletions - determined by the user)
pval = chi sqaure test p value (chance of finding the observed vs expected probability)
