Zhou2018 et al. 2018 map RNA modification of pseudouridine \(\Psi\) by chemically modifying pseudouridines with carbodiimide (+CMC) and detecting arrest events that are induced by reverse transcription stops in high-throughput sequencing under 3 different conditions (HIVRT, SIIIMn, and SIIIMg). Result are for running JACUSA2 rt-arrest on processed pairwise +CMC and -CMC(control) data in SIIIRTMn condition are presented.

Usage

data(SIIIRTMn_rt_arrest)

Format

a tibble with 22 elements:

  • id: Character string representing a unique identifier - created from contig, start, [end], and strand.

  • contig: Character string representing the contig of the variant

  • start: Numeric position of variant (>=0)

  • end: Numeric corresponds to "start + 1"

  • name: Character string. Name of used method call-2

  • pvalue: Numeric value representing the pvalue of the test.

  • strand: Character representing strand information; "+", "-", or "."(no strand information available)

  • arrest: Numeric tibble with representing counts for A, C, G, and T base calls from arrest reads.

  • through: Numeric tibble with representing counts for A, C, G, and T base calls from through reads.

  • bases: Numeric tibble with representing counts for A, C, G, and T base calls.

  • cov: Numeric value indicating the read coverage for this site

  • arrest_rate: Numeric tibble representing the arrest rate for each sample.

  • arrest_score: Numeric - test-statistic score.

  • backtrack1: Character - indicator if backtracking was used for condition 1.

  • backtrack2: Character - indicator if backtracking was used for condition 2.

  • backtrackP: Character - indicator if backtracking was used for condition pooled condition.

  • reset1: Character - indicator if default estimation was unstable with for condition 1.

  • reset2: Character - indicator if default estimation was unstable with for condition 2.

  • resetP: Character - indicator if default estimation was unstable with for pooled condition.

  • info: Character string separated with ";" provding additional data for this specific site. Empty field is equal to "*"

  • filter: ";"-separated character string showing feature filter information. Empty field is equal to "*"

  • ref: Character "A", "C", "G", "T", or "N" representing the reference base for this site - inverted when strand is "-".
