Preprocessing for EZStat format
Would it be possible to add a read routine for the EZStat file format which has frequency, |Z|, phase, Re{Z} and -Im{Z} as its 5 columns with a header line. The specific EZStat code would be as follows:
def readEZStat(filename): """ function for reading EZStat csv files Parameters ---------- filename: string Filename of .csv file to extract impedance data from Returns ------- frequencies : np.ndarray Array of frequencies impedance : np.ndarray of complex numbers Array of complex impedances """ data = np.genfromtxt(filename, delimiter=',')
f = data[1:, 0]
Z = data[1:, 3] - 1j*data[1:, 4]
return f, Z
@xraymancs i think it would help if you could provide a couple sample data files? that way they can add some tests too!
Yep, agree with @hkennyv! An example file (even with fake data) would be really helpful here @xraymancs
Sorry about the delay, Here it is. I believe that this is the default but it would be more fault tolerant if the input routine would use the column headings to determine what to read in. I cannot guarantee that the order of the columns is always the same as what I get from my instrument. I do note that the subtraction that I showed in my code snippet is necessary asn the file has already applied a negative to the data.

I don't think the attachment worked if there was one? (At least I can't see in on the github website)
I attached it to the email. Should I put it directly on github?
