Error Metrics

The ErrorMetricsOut.bin InterOp file contains a the error in Phi X alignment for each tile on each cycle.

% Error After 35 Cycles Per Lane

The average (+/- the standard deviation) of the Phi X error rate for all tiles in a lane for the first 35 cycles of a given read. If an error rate value is not present for any of the first 35 cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles". If a read has less than 35 cycles, then the last cycle is dropped.

% Error After 50 Cycles Per Lane

The average (+/- the standard deviation) of the Phi X error rate for all tiles in a lane for the first 50 cycles of a given read. If an error rate value is not present for any of the first 50 cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles". If a read has less than 50 cycles, then the last cycle is dropped.

% Error After 75 Cycles Per Lane

The average (+/- the standard deviation) of the Phi X error rate for all tiles in a lane for the first 75 cycles of a given read. If an error rate value is not present for any of the first 75 cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles". If a read has less than 75 cycles, then the last cycle is dropped.

% Error After 100 Cycles Per Lane

The average (+/- the standard deviation) of the Phi X error rate for all tiles in a lane for the first 100 cycles of a given read. If an error rate value is not present for any of the first 100 cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles". If a read has less than 100 cycles, then the last cycle is dropped.

% Error

Lane

The average (+/- the standard deviation) of the Phi X error rate for all tiles in a lane for a given read. If an error rate value is not present for any cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles", so the last cycle is not included.

Read

The average of the Phi X error rate for all tiles over all lanes for a given read. If an error rate value is not present for any cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for a given read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles", so the last cycle is not included.

Non-Indexed Total

The average of the Phi X error rate for all tiles over all non-indexed reads. If an error rate value is not present for any cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for any non-indexed read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles", so the last cycle is not included.

Total

The average of the Phi X error rate for all tiles over all reads. If an error rate value is not present for any cycles in the read for a given tile, it is excluded from the averaging. If no tiles have any error statistics for any read, a value of 0 is returned. Note that the base unit for this is the error rate for a single tile - in other words, we average the per-cycle error rate across all the relevant cycles for a tile before calculating these statistics. This is calculated only over "usable cycles", so the last cycle is not included.
