This new release of our genome-wide imputation pipeline includes the following changes:
- The `impute2-merger` tool now merges the marker-wise information file produced for each segment (`*.impute2_info`) into a single file (in the `final_impute2` directory of each chromosome).
- The `impute2-extractor` tool can now extract markers according to their information value (along with other metrics, such as genomic locations, minor allele frequency and call rate).
- Minor bug fixed in the `impute2-extractor` tool, where minor allele frequency was computed using all probabilities instead of filtering out values lower than the specified threshold.
In brief, this release now takes into account the information file provided by IMPUTE2. This information file includes the measure of the observed statistical information associated with the allele frequency estimate. More information about this metric is available [here](https://mathgen.stats.ox.ac.uk/impute/impute_v2.htmlinfo_metric_details).
