-``SENSORS`` - List of sensors to include in the pipeline that have to match existent tables in your AWARE_ database. See SENSORS_ variable in ``config`` file.
-``FITBIT_TABLE`` - The name of table in your database that contains Fitbit data. Its ``fitbit_data`` field should contain the data coming from the Fitbit API in JSON format.
-``PID`` - The list of participant ids to be included in the analysis. These should match the names of the files created in the ``data/external`` directory (:ref:`see more details<db-configuration>`).
-``DAY_SEGMENTS`` - The list of day epochs that features can be segmented into: ``daily``, ``morning`` (6am-12pm), ``afternnon`` (12pm-6pm), ``evening`` (6pm-12am) and ``night`` (12am-6am). This list can be modified globally or on a per sensor basis. See DAY_SEGMENTS_ in ``config`` file.
-``TIMEZONE`` - The time zone where data was collected. Use the timezone names from this `List of Timezones`_. Double check your chosen name is correct, for example US Eastern Time is named New America/New_York, not EST.
-``DATABASE_GROUP`` - The name of your database credentials group, it should match the one in ``.env`` (:ref:`see the datbase configuration<db-configuration>`).
On any given day, Aware could have sensed data only for a few minutes or for 24 hours. Daily estimates of features should be considered more reliable the more hours Aware was running and logging data (for example, 10 calls logged on a day when only one hour of data was recorded is a less reliable measurement compared to 10 calls on a day when 23 hours of data were recorded.
Therefore, we define a valid hour as those that contain at least a certain number of valid bins. In turn, a valid bin are those that contain at least one row of data from any sensor logged within that period. We divide an hour into N bins of size ``BIN_SIZE`` (in minutes) and we mark an hour as valid if contains at least ``MIN_BINS_PER_HOUR`` of valid bins (out of the total possible number of bins that can be captured in an hour i.e. out of 60min/``BIN_SIZE`` bins). Days with valid sensed hours less than ``MIN_VALID_HOURS`` will be excluded form the output of this file. See PHONE_VALID_SENSED_DAYS_ in ``config.yaml``.
In RAPIDS, you will find that we use ``phone_sensed_bins`` (a list of all valid and invalid bins of all monitored days) to improve the estimation of features that are ratios over time periods like ``episodepersensedminutes`` of :ref:`Screen<screen-sensor-doc>` or for resampling data like fused location coordinates.
day_segment The particular ``day_segment`` that will be analyzed. The available options are ``daily``, ``morning``, ``afternoon``, ``evening``, ``night``

day_segment The particular ``day_segment`` that will be analyzed. The available options are ``daily``, ``morning``, ``afternoon``, ``evening``, ``night``
features Features to be computed. Note that the same features are available for both ``incoming`` and ``outgoing`` calls, while ``missed`` calls has its own set of features. See :ref:`Available Incoming and Outgoing Call Features <available-in-and-out-call-features>` Table and :ref:`Available Missed Call Features <available-missed-call-features>` Table below.
entropyduration nats The estimate of the Shannon entropy for the the duration of all the calls of a particular ``call_type`` during a particular ``day_segment``.
countmostfrequentcontact calls The number of calls of a particular ``call_type`` during a particular ``day_segment`` of the most frequent contact throughout the monitored period.
countmostfrequentcontact calls The number of ``missed`` calls during a particular ``day_segment`` of the most frequent contact throughout the monitored period.
Aware Android client stores call types 1=incoming, 2=outgoing, 3=missed while Aware iOS client stores call status 1=incoming, 2=connected, 3=dialing, 4=disconnected. We extract iOS call types based on call status sequences: (1,2,4)=incoming=1, (3,2,4)=outgoing=2, (1,4) or (3,4)=missed=3. Sometimes (due to a possible bug in Aware) sequences get logged on the exact same timestamp, thus 3-item sequences can be 2,3,4 or 3,2,4. Although iOS stores the duration of ringing/dialing stages for missed calls, we set it to 0 to match Android.
day_segment The particular ``day_segment`` that will be analyzed. The available options are ``daily``, ``morning``, ``afternoon``, ``evening``, ``night``

single_categories App categories to be included in the feature extraction computation. See ``APPLICATION_GENRES`` in this file to add new categories or use the catalogue we provide and read :ref:`Assumtions and Observations <applications-foreground-observations>` for more information.
multiple_categories You can group multiple categories into meta categories, for example ``social: ["socialnetworks", "socialmediatools"]``.
single_apps Apps to be included in the feature extraction computation. Use their package name, for example, ``com.google.android.youtube`` or the reserved word ``top1global`` (the most used app by a participant over the whole monitoring study).
excluded_categories App categories to be excluded in the feature extraction computation. See ``APPLICATION_GENRES`` in this file to add new categories or use the catalogue we provide and read :ref:`Assumtions and Observations <applications-foreground-observations>` for more information.
excluded_apps Apps to be excluded in the feature extraction computation. Use their package name, for example: ``com.google.android.youtube``
count apps Number of times a single app or apps within a category were used (i.e. they were brought to the foreground either by tapping their icon or switching to it from another app).
timeoffirstuse contacts The time in minutes between 12:00am (midnight) and the first use of a single app or apps within a category during a ``day_segment``.
timeoflastuse minutes The time in minutes between 12:00am (midnight) and the last use of a single app or apps within a category during a ``day_segment``.
frequencyentropy nats The entropy of the used apps within a category during a ``day_segment`` (each app is seen as a unique event, the more apps were used, the higher the entropy). This is especially relevant when computed over all apps. Entropy cannot be obtained for a single app.
Features can be computed by app, by apps grouped under a single category (genre) and by multiple categories grouped together (meta categories). For example, we can get features for Facebook, for Social Network Apps (including Facebook and others) or for a meta category called Social formed by Social Network and Social Media Tools categories.
We provide three ways of classifying and app within a category (genre): a) by automatically scraping its official category from the Google Play Store, b) by using the catalogue created by Stachl et al. which we provide in RAPIDS (``data/external/``), or c) by manually creating a personalized catalogue.
The way you choose strategy a, b or c is by modifying ``APPLICATION_GENRES`` keys and values. Set ``CATALOGUE_SOURCE`` to ``FILE`` if you want to use a CSV file as catalogue (strategy b and c) or to ``GOOGLE`` if you want to scrape the genres from the Play Store (strategy a). By default ``CATALOGUE_FILE`` points to the catalogue created by Stachl et al. (strategy b) and you can change this path to your own catalogue that follows the same format (strategy c). In addition, set ``SCRAPE_MISSING_GENRES`` to true if you are using a FILE catalogue and you want to scrape from the Play Store any missing genres and ``UPDATE_CATALOGUE_FILE`` to true if you want to save those scrapped genres back into the FILE.
The genre catalogue we provide was shared as part of the Supplemental Materials of Stachl, C., Au, Q., Schoedel, R., Buschek, D., Völkel, S., Schuwerk, T., … Bühner, M. (2019, June 12).

day_segment The particular ``day_segment`` that will be analyzed. The available options are ``daily``, ``morning``, ``afternoon``, ``evening``, ``night``
avgconsumptionrate episodes/hours The average of all episodes’ consumption rates. An episode’s consumption rate is defined as the ratio between its battery delta and duration
maxconsumptionrate episodes/hours The highest of all episodes’ consumption rates. An episode’s consumption rate is defined as the ratio between its battery delta and duration

iOS Activity Recognition data labels are unified with Google Activity Recognition labels: "automotive" to "in_vehicle", "cycling" to "on_bicycle", "walking" and "running" to "on_foot", "stationary" to "still". In addition, iOS activity pairs formed by "stationary" and "automotive" labels (driving but stopped at a traffic light) are transformed to "automotive" only.
In AWARE, Activity Recognition data for Google (Android) and iOS are stored in two different database tables, RAPIDS (via Snakemake) automatically infers what platform each participant belongs to based on their participant file (``data/external/``) which in turn takes this information from the ``aware_device`` table (see ``optional_ar_input`` function in ``rules/features.snakefile``).
day_segment The particular ``day_segment`` that will be analyzed. The available options are ``daily``, ``morning``, ``afternoon``, ``evening``, ``night``
are computed. See Ian Barnett, Jukka-Pekka Onnela, Inferring mobility measures from GPS traces with missing data, Biostatistics, Volume 21, Issue 2, April 2020, Pages e98–e112, https://doi.org/10.1093/biostatistics/kxy059. The code for these features was made open source by Ian Barnett (https://scholar.harvard.edu/ibarnett/software/gpsmobility).
location_to_use The specifies what type of location data will be use in the analysis. Possible options are ``ALL``, ``ALL_EXCEPT_FUSED`` OR ``RESAMPLE_FUSED``
accuracy_limit This is in meters. The sensor drops location coordinates with an accuracy higher than this. This number means there's a 68% probability the true location is within this radius specified.
hometime minutes Time at home. Time spent at home in minutes. Home is the most visited significant location between 8 pm and 8 am including any pauses within a 200-meter radius.
disttravelled meters Total distance travelled over a day (flights).
rog meters The Radius of Gyration (rog) is a measure in meters of the area covered by a person over a day. A centroid is calculated for all the places (pauses) visited during a day and a weighted distance between all the places and that centroid is computed. The weights are proportional to the time spent in each place.
maxdiam meters The maximum diameter is the largest distance between any two pauses.
maxhomedist meters The maximum distance from home in meters.
siglocsvisited locations The number of significant locations visited during the day. Significant locations are computed using k-means clustering over pauses found in the whole monitoring period. The number of clusters is found iterating k from 1 to 200 stopping until the centroids of two significant locations are within 400 meters of one another.
siglocentropy nats Shannon’s entropy measurement based on the proportion of time spent at each significant location visited during a day.
circdnrtn A continuous metric quantifying a person’s circadian routine that can take any value between 0 and 1, where 0 represents a daily routine completely different from any other sensed days and 1 a routine the same as every other sensed day.
Types of location data to use. Aware Android and iOS clients can collect location coordinates through the phone's GPS or Google's fused location API. If your Aware client was ONLY configured to use GPS set ``location_to_use`` to ``ALL``, if your client was configured to use BOTH GPS and fused location set ``location_to_use`` to ``ALL_EXCEPT_FUSED`` to ignore fused coordinates, if your client was configured to use fused location set ``location_to_use`` to ``RESAMPLE_FUSED``. ``RESAMPLE_FUSED`` takes the original fused location coordinates and replicates each pair forward in time as long as the phone was sensing data as indicated by ``phone_sensed_bins`` (see :ref:`Phone valid sensed days <phone-valid-sensed-days>`), this is done because Google's API only logs a new location coordinate pair when it is sufficiently different from the previous one.
Significant locations are determined using K-means clustering on locations that a patient visit over the course of the period of data collection. By setting K=K+1 and repeat clustering until two significant locations are within 100 meters of one another, the results from the previous step (K-1) can be used as the total number of significant locations. Taken from `Beiwe Summary Statistics`_.
(i.e., The length of time and distance a person has to be around the same place to be labelled as a pause)
This is based on a Pause-Flight model, The parameters used are a minimum pause duration of 300sec and a minimum pause distance of 60m. See the `Pause-Flight Model`_.

firstuseafter seconds Seconds until the first unlock episode.
An ``unlock`` episode is considered as the time between an ``unlock`` event and a ``lock`` event. iOS recorded these episodes reliably (albeit some duplicated ``lock`` events within milliseconds from each other). However, in Android there are some events unrelated to the screen state because of multiple consecutive ``unlock``/``lock`` events, so we keep the closest pair. In our experiments these cases are less than 10% of the screen events collected. This happens because ``ACTION_SCREEN_OFF`` and ``ON`` are "sent when the device becomes non-interactive which may have nothing to do with the screen turning off". Additionally, in Android it is possible to measure the time spent on the ``lock`` screen before an ``unlock`` event as well as the total screen time (i.e. ``ON`` to ``OFF``) but we are only keeping ``unlock`` episodes (``unlock`` to ``OFF``) to be consistent with iOS.
