vetschn / eclabfiles Goto Github PK

As mentioned in the previous issue, I am writing a .mpr reader for ixdat making use of eclabfiles, but get errors on many of the files.
For CVA, I get the error "Error: 51". I get this same error whether using
data, meta = eclabfiles.process("05_O2dose_COox_02_CVA_C01.mpr")
or
df = eclabfiles.to_df("05_O2dose_COox_02_CVA_C01.mpr")

The file is here, along with plots of the data (made with ixdat.Measurement.read("05_O2dose_COox_02_CVA_C01.mpt").plot() as demo'd in "plot_data.py"):

Happy for any help or suggestions!

Hi @vetschn ,

Great to see this package!

I am the main author of an open source project "ixdat" which also includes many python parsers for experimental data formats, including Biologic's .mpt. I'm trying to add a .mpr parser which makes use of eclabfiles for parsing the binary file.

eclabfiles works for some files but not others. For details, see this PR: ixdat/ixdat#134

Briefly, it seems to work for LSV measurements, but not CA or CVA. It's a different error message, so I'll put CA here and CVA in a separate issue.

The error I get is "Error: field '(Q-Qo)' occurs more than once". I get this same error whether using
data, meta = eclabfiles.process("05_O2dose_COox_04_CA_C01.mpr")
or
df = eclabfiles.to_df("05_O2dose_COox_04_CA_C01.mpr")

The file is here, along with plots of the data (made with ixdat.Measurement.read("05_O2dose_COox_04_CA_C01.mpt").plot() as demo'd in "plot_data.py"):

Hi,

after updating EC Lab, the data are not supported anymore in eclabfiles library. I tried to fix it on my own, but I could not manage it.

Whenever I try to process new EC Lab data, it shows me following error message:

File ~\AppData\Roaming\Python\Python311\site-packages\eclabfiles\mpr.py:504 in _process_settings
technique, params_dtype = technique_params_dtypes[data[0x0000]]

KeyError: 48

I checked data structure of old EC Lab data and there are some differences. Could you please help me with this problem and tell me how the library should be changed accordingly?

Thanks a lot in advance. By request I can provide a raw data.

All the best:)

I have a question about processing mpr files.

1. def process:
   module_header_dtype = np.dtype([("short_name", "|S10"), ("long_name", "|S25"), ("length", "<u4"), ("version" , "<u4"), ("date", "|S8")])
   in this function, could you explain the purpose of this line?

2. def _process_data:
   n_datapoints = _read_value(data, 0x0000, "<u4")
   n_columns = _read_value(data, 0x0004, "|u1")
   column_ids = _read_values(data, 0x0005, "<u2", n_columns)
   when I run this code, only the first 21 columns are converted. How can I convert all of the flag_columns and data_columns?

thank you

Hello, i'm getting this error when trying to read MPR files.

in _read_value:
Line 444: if dtype == "pascal":

TypeError: data type 'pascal' not understood

Hallo Nicolas,

I want to read mpt or mpr Files 'to_df' but due to the german system we are working on our decimal separators are comma. Is there a way to replace all comma with dots during import.

Example:
df = eclabfiles.to_df(filename)

My df type for a comma value is a tuple. For example I have got a value of 2,5V in my df the value is 2,5 but as [2, 5]. Do I need to combine all tuples and convert them to float?

I think there were changes with the recent update to eclab that affected other things as well as this library... This is the error I get.
Traceback (most recent call last): File "MY_FILE_PATH/FILE.py", line 44, in <module> data, meta = ecf.process(file_path) ^^^^^^^^^^^^^^^^^^^^^^ File "MY_FILE_PATH/FILE.py", line 75, in process return mpr.process(fn, encoding=encoding) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "MY_FILE_PATH/FILE.py", line 686, in process settings, params = _process_settings(module_data) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "MY_FILE_PATH/FILE.py", line 504, in _process_settings technique, params_dtype = technique_params_dtypes[data[0x0000]] ~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^ KeyError: 48

I can still process files made with previous versions of ec lab.
Sorry if there's not enough info -- I can provide
