Fermy is a toolkit to empower fermentation data analysis independent of any SCADA.
Input data have to be converted in Python Pandas DataFrame with datetime or deltatime converted into float as index.
Fermy is composed of two sub-modules:
- pandasfermy add to Pandas methods to compute specific analysis on fermentation data e.g. with growth rate and lagtime calculation with DataFrame.fermgrowth()
- plotlyfermy add to Pandas methods to plot fermentation data with dedicated kinds of charts like Control Chart or Multi-Yaxis Chart e.g. DataFrame.fccplot().
Fermy also includes drivers for laboratory devices like scales (Sartorius Entris or Entris II), peristaltic pumps (Watson Marlow pump 120U connect to a computer through a Labjack T7) & Mettler Toledo sensor mount transmitter as new classes: **PompWatMarlo**, **BalanceEntris**, **MTPReader** & **M80**.
To access to those drivers just make **"import fermy.driverslabtool"** and then **"fermy.driverslabtool.pumps.\<ClassName\>"** or **"fermy.driverslabtool.scales.\<ClassName\>"** or **"fermy.driverslabtool.probes.\<ClassName\>"**.
Fermy also includes "CINAC" like calculations from DataFrame with pH values in columns and time in minutes as float as index.
To access to those tool just make **"import fermy.CINAC"** and then new methods are available **DataFrame.cinac() & DataFrame.inter()**.
Fermy also includes support for Micro Titer Plate (MTP) like 96-well readers from many brands.
To access to those function just make **"import fermy.MTP"**.
The project is hosted on https://gitlab.com/

Methods from pandasfermy
-------------------------
- **fermgrowth:** Function to compute maximal growth rate and lagtime. It is based on a mix of two algorithms describes in Toussaint et al. 2006 and Hall et al. 2014.
* Input: A DataFrame with only data considered as proxy of biomass can be used. DataFrame index has to be a float corresponding to a delta time (in hours) or pandas.DatetimeIndex
* Parameters:
* usemax: allow users by use chose between normalization methods: average of the first five points (by default) or percentage of the maximal value of dataset
* percentofmax: allow users to change the percentage of maximal value used
* timethreshold: allow users to compute growth rate without considering data from time before the provided number of hours
* deltathreshold: allow users to exclude data without a minimal Biomass proxy delta between min and max of the column
* percentegra: allow users to change the % used to select the relevent slope area (EGRA) variation of max slope by default 95% (0.95) of max slope.
* Output: return a DataFrame with lagtime and maximal growth rate
- **fermmultiaux:** Function to compute growths rates and lagtimes for multiauxies It is based on a mix of two algorithms describes in the following: Toussaint et al. 2006 and Hall et al. 2014. Whereas growth rates are found with local max computation.
* Input: A DataFrame with only data considered as proxy of biomass can be used. DataFrame index has to be a float corresponding to a delta time (in hours) or pandas.DatetimeIndex
* Parameters:
* usemax: allow users by use chose between normalization methods: average of the first five points or percentage of the maximal value of dataset
* percentofmax: allow users to change the percentage of maximal value used
* Output: return a DataFrame with lagtimes and growth rates
- **multirename:** Function to rename from a dictionary in forme \{\"newname\" \: (possibleoldname1, possibleoldname2)\} and rename columns in a DataFrame like possiblename1 ==> new name.
* Input: DataFrame, Dictionary with key as new column name and values list of values possibly used in the Dataframe as columns
* Output: return a DataFrame with new columns names
- **replicates("SeparationCharacter"):** Function to average data from a pandas DataFrame grouping by left part of column name after splitting it by a defined separated character (sepchar).
* Input: DataFrame with columns name with pattern "commonpartSEPCHARuniqueid", The character that separate base name to sample identification
* Output: return a DataFrame with averaged data per base name
Methods from plotlyfermy
-------------------------
- **fccplot:** Function to compute and plot a simple (and pretty) Control Chart with Plotly express.

* dicorename: allow users to custom names of axis with {"old name" : "desired name"}.
* forcepower: allow users to force scientific notation 10^n for the y-axis and control limits.
* addccviol: allow users to add a new column to original data with CC rules check-in.
* colorby: allow users to color data help to one column values
* outref: allow users to compute ULC, LCL and mean from given data (pd.Series)
* hql: allow to plot high quality limit
* lql: allow to plot low quality limit
* overinfo: allow to request additional information on ccplot

Growth Rate Algorithm Description
----------------------------------
1. Normalization of data with two user-defined ways. First by divided all data points by a percentage (5 % percent by default) of the maximum value of the distribution. This option may be used if initial data are very noisy (e.g. Biomass proxy coming from a lab scale). Second method divide all data points by the average of the first five points (like in Toussaint et al. 2006). To be more robust regarding next steps each values under 1 is replaced by 1.
2. Then natural logarithm is applied to the normalized data like in Toussaint et al. 2006
3. A smoothing procedure is applied to the corrected biomass proxy by averaging each point with its eight closest neighbors like in Toussaint et al. 2006.
4. The slope of each point was obtained by calculating the slope between the two fourth neighboring points on each side like in Toussaint et al. 2006.
5. The exponential growth rate area (EGRA) is defined where slopes are equal to or greater than 95% of the maximum slope value like in Hall et al 2014.
6. Finally, linear regression is calculated in the EGRA and the slope of the regression gives the maximum (specific) growth rate and the intercept gives Lag time.
Biological signification
---------------------------
- The maximum (specific) growth rate (commonly express in per hours) is the growth rate during logarithmic growth phase (in batch culture) corresponding to the maximum value for the specific condition.
- Lag time (commonly express in hours) is the duration of the phase where growth is absent at the beginning of the culture.

Normalization of data with two user-defined ways. First by divided all data points by a percentage (5 % percent by default) of the maximum value of the distribution. This option may be used if initial data are very noisy (e.g. Biomass proxy coming from a lab scale). Second method divide all data points by the average of the first five points (like in Toussaint et al. 2006). To be more robust regarding next steps each values under 1 is replaced by 1.\r\n2. Then natural logarithm is applied to the normalized data like in Toussaint et al. 2006\r\n3. A smoothing procedure is applied to the corrected biomass proxy by averaging each point with its eight closest neighbors like in Toussaint et al. 2006.\r\n4. The slope of each point was obtained by calculating the slope between the two fourth neighboring points on each side like in Toussaint et al. 2006.\r\n5. The exponential growth rate area (EGRA) is defined where slopes are equal to or greater than 95% of the maximum slope value like in Hall et al 2014.\r\n6. Finally, linear regression is calculated in the EGRA and the slope of the regression gives the maximum (specific) growth rate and the intercept gives Lag time.\r\n\r\nBiological signification\r\n---------------------------\r\n\r\n- The maximum (specific) growth rate (commonly express in per hours) is the growth rate during logarithmic growth phase (in batch culture) corresponding to the maximum value for the specific condition.\r\n- Lag time (commonly express in hours) is the duration of the phase where growth is absent at the beginning of the culture.\r\n\r\nBibliography\r\n-------------\r\n\r\n- Hall B.G., Acar H., Nandipati A. and Barlow M.
