unisensFolder |
String containing path to Unisens folder. |
id |
String containing ID of the signal entry. |
startIndex |
Integer of the value-index on which the read process starts, default: 1. |
endIndex |
Integer of the value-index on which the read process ends, default: last Index of file. |
readInChunks |
Boolean determines if the reading process is done in chunks. This could be useful if you run into memory limits when reading big files. default: FALSE. |
readChunkSize |
Integer defining the size of chunks if chunk reading is enabled, defined in samples, default: 2^16. |
