Hello everyone, I'd like to run each step of the workflow individually, so I followed the instructions of the vignette "introduction to the TPP package for analyzing Thermal Proteome Profiling data: Temperature range (TR) or concentration compound range (CCR) experiments" with the "hdacTR_smallExample" data to see how it works as shown bellow :

data("hdacTR_smallExample")
trData <- tpptrImport(configTable = hdacTR_config, data = hdacTR_data)
normResults <- tpptrNormalize(data = trData)
trDataNormalized <- normResults[["normData"]]
trDataHDAC <- lapply(trDataNormalized, function(d) d[Biobase::featureNames(d) %in% hdac_targets,])

Data import and normalization went well (see bellow), but when I tried to import and use Biobase, the console says that the object 'hdac_targets' is not found. should usually the program create this object or did I miss a step ?

> trData <- tpptrImport(configTable = hdacTR_config, data = hdacTR_data)
Importing data...

Comparisons will be performed between the following experiments:
Panobinostat_1_vs_Vehicle_1
Panobinostat_2_vs_Vehicle_2


The following valid label columns were detected:
126, 127L, 127H, 128L, 128H, 129L, 129H, 130L, 130H, 131L.

Importing TR dataset: Vehicle_1
Removing duplicate identifiers using quality column 'qupm'...
508 out of 508 rows kept for further analysis.
  -> Vehicle_1 contains 508 proteins.
  -> 504 out of 508 proteins (99.21%) suitable for curve fit (criterion: > 2 valid fold changes per protein).

Importing TR dataset: Vehicle_2
Removing duplicate identifiers using quality column 'qupm'...
509 out of 509 rows kept for further analysis.
  -> Vehicle_2 contains 509 proteins.
  -> 504 out of 509 proteins (99.02%) suitable for curve fit (criterion: > 2 valid fold changes per protein).

Importing TR dataset: Panobinostat_1
Removing duplicate identifiers using quality column 'qupm'...
508 out of 508 rows kept for further analysis.
  -> Panobinostat_1 contains 508 proteins.
  -> 504 out of 508 proteins (99.21%) suitable for curve fit (criterion: > 2 valid fold changes per protein).

Importing TR dataset: Panobinostat_2
Removing duplicate identifiers using quality column 'qupm'...
509 out of 509 rows kept for further analysis.
  -> Panobinostat_2 contains 509 proteins.
  -> 499 out of 509 proteins (98.04%) suitable for curve fit (criterion: > 2 valid fold changes per protein).

Creating normalization set:
    1. Filtering by non fold change columns:
Filtering by annotation column(s) 'qssm' in treatment group: Vehicle_1
  Column qssm between 4 and Inf-> 312 out of 508 proteins passed.

312 out of 508 proteins passed in total.

Filtering by annotation column(s) 'qssm' in treatment group: Vehicle_2
  Column qssm between 4 and Inf-> 362 out of 509 proteins passed.

362 out of 509 proteins passed in total.

Filtering by annotation column(s) 'qssm' in treatment group: Panobinostat_1
  Column qssm between 4 and Inf-> 333 out of 508 proteins passed.

333 out of 508 proteins passed in total.

Filtering by annotation column(s) 'qssm' in treatment group: Panobinostat_2
  Column qssm between 4 and Inf-> 364 out of 509 proteins passed.

364 out of 509 proteins passed in total.

    2. Find jointP:
Detecting intersect between treatment groups (jointP).
-> JointP contains 261 proteins.

    3. Filtering fold changes:
Filtering fold changes in treatment group: Vehicle_1
  Column 7 between 0.4 and 0.6 -> 30 out of 261 proteins passed
  Column 9 between 0 and 0.3 -> 223 out of 261 proteins passed
  Column 10 between 0 and 0.2 -> 233 out of 261 proteins passed
22 out of 261 proteins passed in total.

Filtering fold changes in treatment group: Vehicle_2
  Column 7 between 0.4 and 0.6 -> 21 out of 261 proteins passed
  Column 9 between 0 and 0.3 -> 215 out of 261 proteins passed
  Column 10 between 0 and 0.2 -> 227 out of 261 proteins passed
14 out of 261 proteins passed in total.

Filtering fold changes in treatment group: Panobinostat_1
  Column 7 between 0.4 and 0.6 -> 34 out of 261 proteins passed
  Column 9 between 0 and 0.3 -> 217 out of 261 proteins passed
  Column 10 between 0 and 0.2 -> 224 out of 261 proteins passed
21 out of 261 proteins passed in total.

Filtering fold changes in treatment group: Panobinostat_2
  Column 7 between 0.4 and 0.6 -> 15 out of 261 proteins passed
  Column 9 between 0 and 0.3 -> 221 out of 261 proteins passed
  Column 10 between 0 and 0.2 -> 225 out of 261 proteins passed
10 out of 261 proteins passed in total.

Experiment with most remaining proteins after filtering: Vehicle_1
-> NormP contains 22 proteins.
-----------------------------------
Computing normalization coefficients:
1. Computing fold change medians for proteins in normP.
2. Fitting melting curves to medians.
-> Experiment with best model fit: Vehicle_1 (R2: 0.9919)
3. Computing normalization coefficients
Creating QC plots to illustrate median curve fits.
-----------------------------------
Normalizing all proteins in all experiments.
Normalization successfully completed!

I believe you missed some steps:

## ----trTargets-------------------------------------------------------------
tr_targets <- subset(TRresults, fulfills_all_4_requirements)$Protein_ID
print(tr_targets)

## ----trHDACTargets---------------------------------------------------------
hdac_targets <- grep("HDAC", tr_targets, value=TRUE)
print(hdac_targets)
