The .cfg file that I'm attempting to read has the frequency and sample rate data as:

60.000000000
1
15360.000000000,42240

Then, when I try to read it, I get:

pyComtrade instance created!
Traceback (most recent call last):
File "example1_l.py", line 44, in
comtradeObj = pyComtrade.ComtradeRecord(dataFile)
File "/home/leonardo/projects/pycomtrade/src/pyComtrade.py", line 105, in init
self.ReadCFG()
File "/home/leonardo/projects/pycomtrade/src/pyComtrade.py", line 210, in ReadCFG
self.lf = int(self.filehandler.readline())
ValueError: invalid literal for int() with base 10: '60.000000000\r\n'

I already have a proposition that I will submit as pull request.

I'm trying start using pyComtrade but example 3 crash. I used Python 3.4.4 [MSC v.1600 32 bit (Intel)] on win32

... otherwise it will be shared among many instatiated objects.

The oscillographic record that I'm trying to read doesn't have some data fields that are currently taken for granted by pycomtrade, hence I get IndexError exception. Those fields are:

on method ReadCFG()
self.rev_year = int(templist[2])

self.primary.append(float(templist[10]))
self.secondary.append(float(templist[11]))
self.PS.append(templist[12])

self.Dccbm.append(templist[3])
self.y.append(int(templist[4]))

and

self.timemul = float(self.filehandler.readline())

I'm proposing a solution through PR. It's based on a simple check of the templist vector length.

Where a wrong result come to my cases while multiple sample rate applied. Here the codes can run after some debugs.

Briefly, a logical mistake results

wrong outputs under multiple sample rate. So some changes in functions below.

def dct_samples(self, data)
--BEFORE
# For each sample rate
for i in range(self.cfg_data['nrates']):
output['samp'].append(data[0]) # Sample rates
output['endsamp'].append(data[1]) # Number of samples
--AFTER
output['samp'].append(data[0]) # Sample rates
output['endsamp'].append(data[1]) # Number of samples

def read_bin_digital(self) && def read_bin_analog(self)
--BEFORE
nS = self.cfg_data['endsamp']
--AFTER
nS = sum(self.cfg_data['endsamp'])

And the core is to get the addition where "# Reading One or Multiple Sample Rates ".

def read(self, cfg_path, dat_path):
......

    # Try to open the config file
    with open(cfg_path, 'r') as cfg_file:

        ......

            # Extracting and testing arguments
            if arg in ['A', 'D']:

            elif arg in ['samples']:
                
                # Number of Sample Rates
                nsamrate = self.cfg_data['nrates']
                
                # Reading each sample rate
                for i in range(nsamrate):
                    # Read line
                    line = cfg_file.readline()
                    if line.rstrip() == '':
                        break

                    # Process line
                    out_dct = self.proc_line(line, arg)
                    if i in range(1):
                        self.cfg_data.update(out_dct)
                        
                    else:
                        for k in list(out_dct.keys()):
                            self.cfg_data[k].append(out_dct[k][0])
                    
            else:

                ......

    ......

I get this error please advice

Hello, sorry I searched for a documentation here and on the website https://pypi.org/project/pyComtrade/ but I found no documentation for it. I looked at the code and saw the example, but it's an example of how to read comtrade files; the description says it's intended to read and write comtrade files, but by looking at the code I couldn't figure out how to write them.

Dear Miguel Moreto,

Thank you very much for this library to open comtrade files! You just made my life so much easier! You deserve an oscar!

Follows the issue description:

If the filepath for *.cfg file don't starts with . the program breaks.
Within the file example1.py
change the line
comtradeObj = pyComtrade.ComtradeRecord('./test_data3/test3.cfg')
to
comtradeObj = pyComtrade.ComtradeRecord('test_data3/test3.cfg')
and you get
No data file content. Use the method ReadDataFile first

raise ValueError("x and y must have same first dimension")
ValueError: x and y must have same first dimension

I do have a proposal to correct the method ReadDataFile(), however I'm still struggling with git and github! ASAP, I'll do a pullrequest. I'm used to mercurial and bitbucket.
