Hi there, Thank you for all the great efforts in collecting this high quality data and uploading it here on Synapse! It seems to me like there are only a few free walking conditions available on Synapse. Would it be possible to investigate this further @kkontson ? **Edit:** To clarify, there currently is free walk data for a single control (WHC014) and three PD participants (NLS187, NLS188 and WPD011) available. I now read that only a subset performed the free walk condition. Is this the entire subset? Many thanks in advance!
