Maximun length in a cell of data matrix

Sylvain

Hello,

I am using data matrix in order to fill loop in open sesame (I find it more convenient loading first the variable then filling the loop by using data matrix).
Anyway my issue is as follow. I have string of 64 characters made of 0 and 1, because I use this binary coding for filling a matrix of square with various patterns represented by these strings.
So I first created lists of stims, then I create a data matrix object from these lists that I use as a loop.
This strategy worked but not with so long strings apparently:

import numpy as np
from datamatrix import DataMatrix


dmSymPract = DataMatrix(length = 15)

dmPractice_Sym_Stim_Coord = list()
dmPractice_Sym_Stim_Correctness = list()

dmPractice_Sym_Stim_Coord.append('0001100000011000001111000111111011111111011001100011110000011000') #1
dmPractice_Sym_Stim_Correctness.append(True)

dmSymPract = DataMatrix(length = 15)
dmSymPract.StimSym = ''

dmSymPract.StimSym[0] = np_Practice_Sym_Stim[0][0] # doesnt work
dmSymPract.StimSym[0] = str(np_Practice_Sym_Stim[0][0]) # doesnt work
dmSymPract.StimSym[0] = '0001100000011000001111000111111011111111011001100011110000011000' # doesnt work

So the traceback I have everytime is:
Traceback:

Thanks for any help!

Damn there is a typo in my script ( but it does not change the issue).
The line:

np_Practice_Sym_Stim = np.stack((np_Practice_Sym_Stim_Coord, np_Practice_Sym_Stim_Correctness), axis=-1)

is actually

np_Practice_Sym_Stim = np.stack((np_Practice_Sym_Stim_Coord, np_Practice_Sym_Stim_Correctness), axis= 1)

Sorry!

Hi Sylvain,

Right—what happens here is that DataMatrix tries to process this string as a number. But because it's such a big number, it becomes a long type, and DataMatrix doesn't accept that. I'll fix this in an upcoming release of DataMatrix. For now, if this is possible, you could use strings that are clearly not numbers, for example prefixing a '_' character or something.

Cheers,
Sebastiaan

Perfect thank you!

Best,

Sylvain
