I imagine there is some good reason for this, but I don't understand this behaviour:

> create_emuRdemoData(dir = tempdir())
> demo_data_dir = file.path(tempdir(), "emuR_demoData")
> tg_col_dir = file.path(demo_data_dir, "TextGrid_collection")
> path2directory = file.path(tempdir(), "my-first_emuDB")
> convert_TextGridCollection(dir = tg_col_dir,
                            dbName = "my-first",
                            targetDir = tempdir(),
                            tierNames = c("Word", "Syllable", "Phoneme", "Phonetic"))
> db_handle = load_emuDB(path2directory, verbose = FALSE)

Now create a seglist:

> sl_vowels = query(db_handle, "Phonetic == @")
> sl_vowels
> sl_vowels
# A tibble: 28 × 16

So far, so good. Now I want session to have some other value:

Note that session is still a <chr>. But now:

> td_vowels = get_trackdata(db_handle,
+                              seglist = sl_vowels,
+                              onTheFlyFunctionName = "forest",
+                              verbose = F)
Error in get_trackdata(db_handle, seglist = sl_vowels, onTheFlyFunctionName = "forest",  : 
  Following utts entry not found: 
In addition: Warning messages:
1: In get_trackdata(db_handle, seglist = sl_vowels, onTheFlyFunctionName = "forest",  :
  The emusegs/emuRsegs object passed in refers to bundles with in-homogeneous sampling rates in their audio files! Here is a list of all refered to bundles incl. their sampling rate: 
[1] session        bundle         media_file     sample_rate    md5_annot_json
<0 rows> (or 0-length row.names)
2: Unknown or uninitialised column: `utts`. 

I am willing to accept that part of the solution here is "don't mess with session, but at the very least, this seems like the wrong error message: nothing has touched the audio files or their sample rates.

I would consider database query results (or at least their session and bundle names) as immutable objects. If you change the session name in the query result, the database will not be updated automagically (by renaming the session). The results are just tibble objects. With the second call to get_trackdata you query bundles of a non-existent session 'F1' and that fails.
I agree that the error message is misleading.
Do you just want to rename the session from '0000' to 'F1' ?

We were just using session as a stand-in for "speaker"; it's simpler to just create a new column. But yes, the idea was just to rename the session(s).
