Confidence intervals of PsN bootstrap output

Hello everyone, I am using PsN to do some bootstrap and have some questions regarding the PsN output. 1. There are two confidence interval (CI) reported in the output file "bootstrap_results.csv": standard.error.confidence.intervals percentile.confidence.intervals I wonder which one should be used in the publication or report, and what is the difference between them. 2. When I use excel function "=PERCENTILE(T5:T505,5%)" and "=PERCENTILE(T5:T505,95%)" to calculate the 5% and 95% percentile of a parameter from the data "raw_results1.csv" the result is different from both "standard.error.confidence.intervals" and " percentile.confidence.intervals". The same happens to the excel function "=MEDIAN(T5:T505)" result and the"medians" in the "bootstrap_results.csv". Does anyone know why it is the case, and which value I should use? bootstrap_results.csv medians 423.5635 standard.error.confidence.intervals 5% 419.73239 95% 428.26761 percentile.confidence.intervals 5% 419.56165 95% 427.9239 Excel calculation from raw_results1.csv Median 423.578 5% percentile 419.593 95% percentile 427.922 Thanks, Norman
