Base call files
Each tile analyzed is included in a base call file, aggregated in a file for each cycle. The
aggregated file contains the base call and encoded quality score for every cluster.
Data\Intensities\BaseCalls\L001
[Cycle].bcl.bgzf, where [Cycle] represents the cycle number in 4 digits. Base call files are
compressed using block gzip compression.
Base call index file
A binary index file lists the original tile information in a pair of values for each tile, which
are tile number and number of clusters for the tile.
Base call index files are created the first time a base call file is created.

s_[Lane].bci
Cluster location files
For each tile, the XY coordinates for every cluster are aggregated into a cluster location
file. Cluster location files are the result of template generation.
Data\Intensities\L001
s_[lane].locs
Filter files
The filter file specifies whether a cluster passed filters. Filter information is aggregated
into a filter file for each read.
Filter files are generated at cycle 26 using 25 cycles of data.

s_[lane].filter
InterOp files
Binary reporting files used for Sequencing Analysis Viewer. InterOp files are updated
throughout the run.
InterOp folder
RTA configuration file
Created at the beginning of the run, the RTA configuration file lists settings for the run.
[Root folder], RTAConfiguration.xml
Run information file
Lists the run name, number of cycles in each read, whether the read is an Index Read,
and the number of swaths and tiles on the flow cell. The run info file is created at the
beginning of the run.
[Root folder], RunInfo.xml
Sequencing Output Folder Structure
The control software generates the output folder name automatically.
